Days between dates, add or subtract time, find weekdays
Need to know how many days until a deadline, how long since an event, or the exact duration between two dates? This calculator gives you the answer in seconds — in days, weeks, months, or years, with weekdays counted separately if needed.
Use the second mode to add or subtract a number of days, weeks, or months from any starting date. Useful for calculating payment due dates, project deadlines, contract end dates, or figuring out what date falls 90 days from today.
