Period length in days, from dates

Usage

period_days(from, to)

Arguments

from

Start of the period: a Date, or anything as.Date() accepts.

to

End of the period, inclusive.

Value

The number of days in the period, for use as t.

Details

Inclusive of both ends, because a period running from the 1st to the 31st is thirty-one days of exposure, not thirty. Leap years need no special handling: the arithmetic is on dates, so 2024 comes out at 366 and 2023 at 365 without anyone choosing.
