What Is the Date Calculator?
Our date calculator lets you calculate the number of days between two dates. You can also use it to add or subtract days, weeks, months, or years to/from a date.
What can I do with the date calculator?
- Count Days: Finds the total number of days between two dates. You can use it to find how many days are left until a specific date, like New Year's Day.
- Add Days: Finds the date after a given period. For example, you can find 9 months and 10 days from today or from a specific date.
- Subtract Days: Finds the date before a given period. For example, you can find the answer to the question "What date was it two weeks ago?".
However, note that this tool does not let you track the time. You can use the online stopwatch, online alarm clock, and online timer for these tasks.

Why Use the Number of Days Between Two Dates Calculator?
Although you can manually count the number of days between two dates, this date calculator makes it quick and simple. When calculating manually, you must consider leap years and varying month lengths. This calculator accounts for them automatically and gives you a precise answer. You can plan your trips and holidays, track deadlines, count the remaining days until your birthday, or calculate age more easily thanks to this tool.
