In many religious calendars, the day goes from sunset to sunset.

When translating to the civil calendar, you can divide that day into two parts: from sunset to midnight (A), and from midnight to the following sunset (B).

For terminology, "eve" works well for part A.

Is there a term for part B?

The closest I've found are "day", "morning" and "morrow". Is there another term that could be used?


I don't think there is a term in English that works.

For my computer code, I decided to call the two parts of the day simply "fragment 1" and "fragment 2." The term "fragment" does not imply how big it is.

Not very elegant, but that worked for my purposes.


ante crespusculum? or ante opacare? In the spirit of AM -- ante meridian?

    A good answer to a single word request explains why the options presented work. – Matt E. Эллен May 6 '15 at 12:56

    Hi Gianni, welcome to ELU. Could you share the definition of those words, and where you found them? That would greatly assist the OP in deciding which answer to choose. Thanks! – erich May 6 '15 at 13:04
