- today is from 00:00.00 this morning until the end of time
- yesterday is from yesterday 00:00.00 until today
- the other ones also mean pretty much exactly what you would expect
them to mean.
- this week and this month both can be empty because they are already
covered by today, yesterday etc. This is by design.
