About This Date Calculator
Need to calculate the number of days between two dates? Want to know what date comes 30, 90, or 120 days from today? Kivixa's Date Calculator makes it easy to calculate date differences, add or subtract days, months, or years, and find future or past dates in just a few clicks.
Unlike a basic date calculator, this tool also includes working day calculations with flexible weekend exclusions. You can exclude all Saturdays, alternate Saturdays (2nd & 4th), all Sundays, or alternate Sundays depending on your work schedule. This makes it useful for project planning, office deadlines, government offices, schools, banks, and businesses that don't follow a standard Monday to Friday calendar.
All calculations are performed instantly in your browser, providing accurate calendar results without page reloads or manual counting.
How to Use the Date Calculator
- Choose Add / Subtract Date or Date Difference.
- Select your base date.
- Enter the number of years, months, or days to add or subtract, or choose a second date for comparison.
