What date is 30 days from today?

A date calculator adds or subtracts days, weeks, months, years or business days to a start date and returns the resulting date, accounting for month lengths and leap years.

Units

Days and weeks — calendar days.
Business days — skips Saturdays and Sundays (e.g. "5 working days").
Months and years — keeps the same day of the month; if it does not exist, the last day of the month is used (31 January + 1 month = 28 February).

Typical uses: contract notice periods, payment terms (net 30), delivery estimates, warranty end dates and project deadlines. Count the days between two dates with the Date Difference Calculator.
