Date Calculator
Need to figure out a deadline, due date, or anniversary? This date calculator adds or subtracts any combination of days, weeks, and months from a starting date and tells you the resulting date, day of the week, and how far it is from today.
The calculator starts from a date you specify as days from today (0 for today, negative numbers for past dates) and then adds or subtracts your chosen duration. Months are added calendar-style, meaning adding 1 month to January 31 gives February 28 (or 29 in a leap year).
This is useful for calculating project deadlines, loan maturity dates, contract expiration, subscription renewal dates, or any scenario where you need to count forward or backward from a known date. The day-of-week output helps with scheduling around weekends and holidays.
For business-day calculations that exclude weekends, use the dedicated Business Days Calculator instead.
