Add days to a date

This tool adds a chosen number of days to a starting date and returns the resulting date, handling the month and year rollovers automatically so you don't have to count on a paper calendar. It's a common one for working out things like a due date, a return-by date, or when a fixed-term period actually ends.

Because it works purely in calendar days rather than business days, a 30-day figure will include any weekends and public holidays that fall inside the span. For calculations that need to skip non-working days, the working-days calculator is the better fit.
