How days between dates are counted

The calculator counts midnights between your two dates — the standard difference, so Jan 1 to Jan 2 is 1 day. The weekday count uses the same convention, counting only Mondays through Fridays in that span. The table re-expresses the exact same gap as weeks + days, whole calendar months, and calendar-accurate years, months and days.
