Calculate a date in the future or past
Start with any calendar date, choose whether to add or subtract, and enter the number of days. This is useful for deadlines, return windows, travel plans, renewal dates, project schedules, and questions such as “what date is 30, 60, or 90 days from now?”
The calculation uses calendar days. If you specifically need Monday-to-Friday working days, use the Business Days Calculator instead.
