We 100% refuse to do that, no way. The data in the calendar table is owned by HR. They update it. If they farm it out to their receptionist, fine with me. It's not a complicated task, but it's just complicated enough that a computer shouldn't be doing it.

We do generate all the official calendars though, so we have print options to print various views of it(paydays, etc) and we also provide .ics feeds for Google/Apple Calendar, etc.
