I think the date selector is a must. My biggest timezone confusion happens during these two weeks when the US changes the daylight and the EU is not changed yet. So... during the two weeks in a year 9:00am SF time is not 18:00 EU time.
Love this! Looks nice (I can't design it), works smoothly. Kudos on you for building something simple and just getting it out there.
Universe knows, there are many bells and whistles you could have tacked on, possibly dooming this project to stay in the "project shelf" for a much longer time.
What's your story on starting this? Needed the tool yourself and couldn't find anything that worked for you, was trying to learn new tools, lost a bet?

If you click on the logo, it shows placeholders for many other time related tools the author has plans to implement like a meeting planner, scheduler, calendar and pomodoro timer etc. I'm happy that they took the MVP approach instead of waiting long to launch that perfect suite.
Might be useful to have the slider cover 3 days, rather than just 24h. With the single day, New York visually looks to be ahead of London at certain times of day (e.g from 00:00 to 05:00 UK time), because NY is still in its previous day.
Awesome tool! Some minor feedback for what it's worth - after moving the slider bar to change the time, I went looking for a button along the top something like "Reset to Now", and it took me about two seconds to realize this reset button was in each time widget frame.
I kind of agree that the "reset to now" button should be in the global context, as resetting each timezone to now separately doesn't make as much sense.
Looks very slick. Using this on an ipad. A few comment... Moving the time slider also moves the zone widget. It would be nice if night/day is indicated on the sluder, maybe using subtle colors. Reason: The main reason I would use such an app is to know if my clients are awake.
Can you add a service worker and manifest to make this into a progressive web app that works offline? If there's a GitHub, I'd love to help add that feature because it'd be useful to me. If it's not public you can find me here https://github.com/gabesullice
That's really nice and coincidentally I needed such a tool just a few days ago.
If I could make a small suggestion - always mark a few key times on the timeline so a user can quickly guesstimate, say, midday here is 9am there without the sliders.
You should be using https://www.timeanddate.com/worldclock/converter.html which is the exact same thing (arguably slightly better with just one slider and color-coded "good" and "bad" times when the timezones overlap)

Not a problem if you aren't playing that game.
I've got a few things out three that probably aren't listed anywhere (they won't be anywhere that respects the robots.txt equivalent of “go forth and fornicate”!). They are there for me, friends, family, or to refer people to when relevant. Heck I might even mention one on public forums occasionally either due to relevance or just for a little mild ego-stroke. But I don't care whether or not they are listed in the first page of Google/Bing/Kagi/… so the general public can easily find them.
Admittedly the general public likely aren't even looking for them, I'm sure they are well served elsewhere, but that is beside the point.
Being massively popular doesn't necessarily imply fame & fortune. It might instead be fame and needing-to-find-a-way-to-pay-for-resources-to-keep-stuff-running-under-high-traffic (and dealing-with-stupid-emails-from-people-who-don't-know-which-elbow-they-are-sat-on!).
Some attention is better than no attention but monetization/a side hustle/etc. just isn’t a big deal for a lot of people and honestly isn’t a real option in a lot of contexts.
https://www.worldtimebuddy.com has a similar design and is configurable. And I prefer it (the slider aligned) to OP's design (sliders all over the place)..
I like the way this tool looks, but I am a big fan of the "row-based" designs from these other tools for comparing time zones.
* Every Time Zone: time zone converter, compare time zone difference and find best time for a meeting with one click || https://everytimezone.com/
* Time Converter and World Clock - Conversion at a Glance - Pick best time to schedule conference calls, webinars, online meetings and phone calls. || https://www.worldtimebuddy.com/
And this site has a bunch of great tools for calculating time between days and a bunch of other miscellaneous stuff.
It allows for a calendar view and shows multiple cities together. It's excellent for figuring out a time slot for a team when everyone is living in a different timezone.
I was thinking of this site as well, showing the different time lines and how they offset according to the time difference. Very neat. Just couldn't remember the domain name.
The design is a bit dated as it's not optimized for higher res screens, everything is quite small. I guess people can zoom in.
How do they make money though? I don't see ads or sign up page for extra features. Running this service since 2011, have to pay for hosting fees etc.
There used to be paid options. They sent a notice a couple years ago saying it was going completely free, but with that support has subsided. For example their mobile app is no longer compatible with latest versions of Android.
I bought the app long ago, but now I have a problem: their database isn't updated. Where I live the weekend changed from Fri/Sat to Sat/Sun since a year, but the app seems abandoned.
Well done! I'd use this over what's out there.
Suggestions:
1. On mobile, it's hard to see more than 2 times without scrolling. I think compress the vertical space more
2. Might be nice to share a link with a configured set.
The only thing I can see missing that I would use would be the ability to select a date in the future or past. Now this might be my ignorance of the subject area but it's definitely something I use other services for.
If you work with people across multiple timezones, it's really useful to be able to open a screen with a set of clocks and glance at the time in every relevant timezone.
If I just have https://time.fyi/timezones bookmarked, it seems to remember the timezones that are important to me. Definitely convenient and far easier than doing multiple searches or using a phone's multiple clocks(?).
This site is useful enough and it's a nice execution.
Nice! I saved to my iPhone Home Screen. However, the icon was a black box with a white T. When I tapped to save it showed a much nicer black box with yellow swirl - looks like an icon file is missing.
This is really cool! Found a small bug - when you add a second card, the second card displays a pill with the total time difference between the first card and second card. When you switch the order of the cards by dragging, the pill remains on the same card so it's basically showing the total time difference in reverse. Clearing the cards and starting over with the switched order but by creating each card again results in the pill being displayed on the correct card.
Nice little idea! As a slight aside I’m not sure where the timezone / city list has come from but it labels Hanoi as in Thailand (rather than Vietnam).
You're brave, dealing with time is often a discouraging and frustrating experience as a developer.
I did bookmark it and I'm curious to see the other features (coming soon), because sharing time-based events on some social platforms isnannoying, and having a way to link to a specific time and date and having each user see the time relative to their timezone in a simple interface would be nice.
I’ve seen “anywhere in earth” [0] used increasingly for deadlines. It’s something I’m looking up in these time zone calculators. You might consider adding it.
Very nice, very useful. The slider is extremely easy & fast input method which is great. I've encountered an issue with the fonts spacing of hours and minutes - the digits are overlapping: https://imgur.com/a/meoRaJL (Win11, Chrome, Firefox, Edge)
Would love to see pr. timezone AM/PM and Military time toggle. I personally not figured out how to mentally convert from one to another and usually this is one of my challenges as well.
I support the link sharing as well. Perfect for events, meetings and the like.
So good, very easy to use and not to much other stuff going on. Great job and super domainname.
your questions are literally the reason why internet is not what it used to be. not everything needs to be about money, people can do things out of their own interest and needs
It seems not to have knowledge about CEST - Central European Summer Time. I am always hesitant when using this term since many are unaware of it, but writing CET while refering to the current (summer) time is technically wrong. I wonder if the user interface somehow can illustrate this.
This is so intuitive. Huge props for coming up with the first ui for time zone comparison that has actually made sense to me immediately. Clicking a zone to make it the base, which all others get compared to, was a great choice. Bookmarking this for sure.
I like this and it’s immediately usable. May I ask you to make it so that I can reorder the boxes. Also could I have an option to have shorter boxes so that I can view 4 time zones without the need to scroll on a mobile screen?
Being someone who lives in Asia and interacts with clients(potential clients) in the Americas, I often find it difficulty to select a timeslot for a meeting. This tool will help a lot.
Very clever solution! Would be cool to add a color coding of the time, maybe same way as Apple does sun position in the weather app. So when you scroll time you can see where of all these places the sun is still up.
Bug report: Typing Oslo, Bergen, or Trondheim shows "Bouvet Island" instead of "Norway". (Bouvet Island, while Norwegian territory, is an uninhabited arctic island.)
Amazingly pretty! I'm not international enough to have a personal use case for this, but I admire the skill that went into this. Are you open sourcing this at some point?
This is going to be my daily driver to schedule our team meetings, great work! A feature request would be to give me the option to input the time apart from the existing slider input.
I'd love to see this with sun position. Maybe even change the brightness of the square too. Then you could visually see when all your meeting participants are in daylight.
The location database has some extremely weird errors in it. For example, Belgrade is shown to be in Kosovo when it is in fact in Serbia. Similar for other Serbian cities.
Awesome thanks for making this! Was just planning a trip to Asia with my wife and had to figure out which days I needed to take off. The app was very useful!
This is a great tool. Thank you. As an international student in US with a lag of 10-12 hours with my home country, this will be very helpful in scheduling calls.
I depends on this, but Google Calendar only lets you add a second time zone. They don't take up much space, I'd love to have 3 or 4. Has anybody figured out a way to do that?
Disagree. It appears to default to your local time zone for the first entry, which is a sane default. If there were other useless (to me) defaults as well I’d have to remove them as visual clutter (in addition to still needing to add the time zones I wish to compare).
- Show the timezone name/descriptor if I select a city (yes, it already says 'GMT+X', but it would be helpful to have the local timezone name of that city as well)
- Somehow select a time for a different day. E.g. if I want to compare the times for the 22nd of October 2024 instead of today (Countries/Cities/Regions swap timezones x-times a year, on different days)
I was thinking it would be cool to add another slider for day of the year. That way you can see how the differences change as local timezones roll through their own daylight savings time or other adjustments. For example, right now Asuncion Paraguay is +3 hours ahead of Chicago U.S. but in April it will be only one hour ahead.
Ah that was intentional, it disables the sorting on smaller screens. I am working on some UI refinement for smaller screens and will re-enable sorting after that.
I actually quite like the amount of dead space, as most time conversion tools I have used have been filled to the gills with information whereas I am typically only looking for one or two specific data points. To be honest, with many time conversion apps I often even struggle to distinguish a meaningful header, main content, and footer as they will often resemble some sort of industrial ticker. I know, different tools for different purposes, but that is exactly why I like this: it achieves simple comparisons simply.
I’m not saying add more things and information. I’m saying the opposite - remove things (white space) so I can look at more than three timezones changing (which is my use case as I run a ticketing site with venues around the world).
I've been a big fan of worldtimebuddy[1] for a long time. I book a lot of meetings across timezones and it's makes it very easy to see when a good time for a meeting would be between sydney tokyo and miami as an example
Out of curiosity, would you prefer to see all the options laid out so you can quickly scan which ones would be optimal? Or would you prefer to click a button and then it just schedules the meeting for you?
I use this. You can easily pick dates (and it correctly handles time changes in one region vs the other) and you see the time bands side by side. Finally, it has a great mobile app, too.
it was regiesterd first in 2015, and has alredy been renewed till 2029-09-02 with cloudflare registrar. It's purchase price was also not a premium at just $18
Your link also has an extra feature that the OP does not.
When I open https://www.timezones.digital/ it asks permission to get my current location and then displays the time for my location. And it even got the city name correct. This is great on mobile.
Whereas https://time.fyi/timezones does not currently request access to location and instead uses the location of my IP address. Which in my case is the location of my ISP and not of myself. Using the name of the city my ISP is in, which is halfway across the country from me.
Getting a location permissions popup the instant you first load a page is an annoyance, imo. Friendlier to leave that as an option you can choose if it looks worth it.
interestingly, that one misnames Rio de Janeiro as "Vila Rio de Janeiro" which is hilarious, considering the Rio metro area has ~12M people, so a bit bigger than my idea of a village
I'm not a fan of the design, tbh. I see no reason why these need to be cards, which actually forces the sliders to be next to each other (rather than below each other or combined into a single slider)
Hey! There was no intention of "stealing." I did not know who else was involved in the development of timezones.digital, and I did send a message to the designer "Mykhailov" about using it as inspiration. The only reasons for redevelopment were:
- The timezone search in the original app was laggy.
- It did not allow searching timezones by offset, e.g., 'GMT+5,' 'gmt-5,' etc.
- It did not allow timezone search by name, e.g., PST, EST, GST, etc.
- It requested location permission that seemed unnecessary.
- It was closed source.
I had been using your product for quite some time and only developed time.fyi to scratch my own itch. I will be open-sourcing it soon and planning on extending it beyond what it is today.
Having said that, thank you for your work on timezones.digital!
If you're one of those "give me a terminal or give me death" master race kind of person, then I have a little shell script I use for this:
% tz
US West 18:39 -0800 PST
US East 21:39 -0500 EST
UTC 02:39 +0000 UTC
Ireland/UK 02:39 +0000 GMT
West Europe 03:39 +0100 CET
New Zealand 15:39 +1300 NZDT
Current 02:39 +0000 GMT
% tz 18:00
US West 10:00 -0800 PST
US East 13:00 -0500 EST
UTC 18:00 +0000 UTC
Ireland/UK 18:00 +0000 GMT
West Europe 19:00 +0100 CET
New Zealand 07:00 +1300 NZDT
Current 18:00 +0000 GMT
I didn't know date supported that – can still do that with "tz '4 hours ago'".
For me the most useful part is being able to quickly translate things like "let's do a video chat at 3pm PST" to something that makes sense, which is why it had the second argument to set the timezone.
Great UI design; clean, intuitive, and useful. Thank you for this!
On a side note, I'd really like to know what broken mechanism aggressively downranks such quality community submissions. 67 upvotes in 2 hours, and only ranked 9th. Meanwhile, another post with fewer upvotes in more time is ranked 2nd. Something is very wrong here. I'd love to see more posts like this one, and fewer standard blog articles that are hitting the front page for the third time in five years.
"The basic algorithm divides points by a power of the time since a story was submitted. Comments in threads are ranked the same way.
Other factors affecting rank include user flags, anti-abuse software, software which demotes overheated discussions, account or site weighting, and moderator action."
I've always been a fan of the https://everytimezone.com interface, which seems like it may have been acquired at some point. Still works brilliantly though!
