The add days to date calculator lets you jump forward or backward any number of days from a starting date. Perfect for calculating due dates, expiration dates, planning ahead, or looking back in time.
Enter your starting date and the number of days to add (positive) or subtract (negative). The calculator handles month and year transitions automatically and even tells you what day of the week the result falls on.
This is incredibly useful for subscription tracking ("30 days from today"), warranty calculations, project milestones, rental periods, or any scenario where you need to know a date a specific number of days away.
