How DayCalcs counts

Counting starts the day after your start date, the way deadlines, notice periods and return windows are usually counted. So 30 days after the 1st of a 31-day month is the 31st.

Months are added by calendar month. If the day doesn't exist in the new month, the date moves to that month's last day, so one month after January 31 is the end of February.

Business days are Monday to Friday. Tick "Skip US holidays" to also skip US federal holidays, moved to the observed weekday when they fall on a weekend.
