It would be nice to have a way to make holidays (and hours eventually) on the calendar public.
A public calendar would be great and particularly with opening hours. Currently the receipts print a date and timestamp with hh:mm:ss with gives a return by "date 23:59:00" which is just plain silly. But since people have hourly loans we can't remove that timestamp. Hence my interest in a public calendar that includes opening hours since we would then have a timestamp that says to return by closing hours. (I'll file a separate bug for the opening hours part and connect them with a see also)
Found 8133 that gives us opening hours and set a "see also".
