Description rwk 2023-07-22 17:16:10 UTC
Hi,
the leap year for the centuries is not calculated correctly before 1600. There should be no February 29th in the years that are multiples of 100 and not multiples of 400. This does work for the centuries 1600 and up into the future, but not going into the past(1500, 1400, 1300..., -200). In the time before 1600 every year dividable by 4 is a leap year, unfortunately all the centuries also. That ruins the day count.  
 
Thanks for considering my input

I'm not sure there is a clear bug or requested behavior here. I understand the general concept, but then I wonder what exactly should be the "expected behavior" vs the "current behavior".

There are several reports regarding Gregorian calendar. One of them is bug 144699.
Comment 2 Regina Henschel 2023-07-23 16:54:15 UTC
The behavior is specified here:
https://docs.oasis-open.org/office/OpenDocument/v1.3/os/part4-formula/OpenDocument-v1.3-os-part4-formula.html#__RefHeading__1018898_715980110

Essential is "proleptic Gregorian system (continuing the years backwards as if the calendar existed in those years)"

rwk: please share more information on what the request is.
