The number of days between two dates is calculated by subtracting the start date from the end date. The calculation can include or exclude the end date depending on the context or preference.
General Method
- Subtract the start date from the end date to get the number of days.
- Optionally, include the end date by adding 1 to the result.
- Weeks between dates can be found by dividing the number of days by 7.
- Months and years between dates depend on calendar specifics such as different days per month and leap years.
Examples
- Between July 4th and July 26th, there are 22 days excluding the end date and 23 days including it.
- To find weeks, divide days by 7 (e.g., 108 days ÷ 7 = 15 weeks and 3 days).
This calculation is based on the Gregorian calendar, which has 365 days a year and 366 days in a leap year.
