What a DatePrimitive says about the dates it holds: music21’s relevance, which is what tells its four date classes apart.

Variants

Certain

The date is the date: music21’s DateSingle('...').

After

After this date, written after ....

OnOrBefore

On this date or before it, written ... or earlier.

OnOrAfter

On this date or after it, written ... or later.

And

All of these dates, written ... and ....
