Question Readability of calendar conversions

If I put it gets displayed as which is going to be confusing to visitors and uninitiated members. Might be better as Maybe there could be an admin option to chose "C.E." or "A.D."

Also, for genealogy, B.C. or B.C.E. might not be useful, but what about history? is currently rendered
I started an experiment with biblical genealogies¹ Since the Hebrew calendar purports to show years from creation, I put the birth of Seth as which is displayed as merely What should be done with that, if anything?

¹The issue is how these dates should be displayed. Whether the bible is history or myth is an hot-button to many but should not be argued here..

You say that you entered but it should be
You are right that the display "5130 (1370)" is not intuitiv. There should be a bit more information shown.

If you enter that is shown as i.e 3760 (hebrew) = 1 BC (Julian) = -1 (Gregorian ???)

Ah, I thought I had seen a different syntax but didn't remember what it was. So I used the syntax in the GEDCOM 7 spec. I would add to my suggestion that webtrees support both input formats as well as improve the display format. And don't forget the discontinuity (the lack of a year zero) in the conversion functions.

You can see the GEDCOM 5.5.1 format when entering a date in webtrees by using the help icon = "?".

You are right, webtrees is already supporting the GEDCOM 7 format using "HEBREW" instead of "@#DHEBREW@" in 5.5.1. There is another change: GEDCOM 5.5.1 is using "B.C.", GEDCOM 7 is using now "BCE". Another miracle: GEDCOM 5.5.1 allows B.C. for the Hebrew calendar. I don't know what the meaning is of that.

Yes, it is nice that webtrees supports already now the GEDCOM 7 keywords for the calendar system. In GEDCOM 7 the "custom" webtrees calendars "Islamic" and "Jalali" should start with an "_" to indicate that they are custom calendar systems.

One minor remark about conversion from the hebrew calendar to the gregorian calendar: this is not exact because of the start of day at sunset or midnight in those calendars.

And yes: the important point in your post is: "present the information in a way that is understandable and clear".
