Date Calculator

Days Between Dates Calculator

This date calculator answers two common questions: how many days are between two dates, and what date is a certain number of days from a starting date. Both calculations update automatically as you type — no button needed.

Days From Today

To find what date is 30 days from today, 60 days from today, or 90 days from today, use the second form. Enter today as your start date and type the number of days. The result date and day of the week appear instantly. You can use any start date — not just today.

Date Difference Calculator

The date difference calculator in the first form shows the number of days between two dates, along with weeks and remaining days. The "include end date" option adds one day to the count — useful when you want to count both the start and end day (for example, a 5-day period from Monday through Friday).

How Many Days Until a Date

To calculate how many days until a specific future date — an event, deadline, or anniversary — set today as your start date and your target date as the end date. The tool also works in reverse for past dates, counting how many days since an event occurred. To find your exact age in years, months, and days, use the age calculator.
