I’m from Germany and my watch is set to German.
When using the #Da# tag, it shows AM and PM in the creator (English). On my watch “vorm.” and “nachm.” (German abbreviations for forenoon and afternoon) are displayed and this may break the design of many watchfaces. Some languages seem to show own terms there, so I wanted to change it to always have AM or PM.
I tried $#Da#==“AM”?AM:PM$ but on my watch it always showed PM, because “vorm.” or “nachm.” will never be AM. For that reason, I now use $#DH#<12?AM:PM$ and that should work in every language.
Just in case you need it.
