The dates can optionally be given more precision with time (their default time is noon, i.e. 12:00:00 UTC), for computing timezones.
This template assumes (but does not check) that date2 comes strictly after date1.

If date3 is the same as date1 then the return value will contain the values of named parameters before or first, between not last, between.
If date3 comes strictly after date1 but before date2 then the return value will contain the values of named parameters between not last, between, between not first, between exclusive.
If date3 is the same as date2 then the return value will contain the values of named parameters between, between no start, after or last.
If date3 comes strictly after date2 then the return value will contain the values of named parameters after or last, after.
