Days Between Dates Calculator

Calculate how many days are between two dates

Understanding the Calculation

The calculation counts the total number of days from the start date to the end date, inclusive of the start date but not the end date. It takes into account leap years, ensuring each February has the correct number of days according to the Gregorian calendar.

This calculation method avoids double counting when consecutive date ranges are added together. By including the start date but excluding the end date, each day is counted only once, even when one range ends on the same day another begins.

For example, if you calculate the days from January 1st to January 3rd, the calculation includes January 1st and January 2nd, but not January 3rd. So, the total number of days would be 2, not 3.

Weekend Exclusion Explained

When the 'Exclude Weekends' option is enabled, the calculator omits Saturdays and Sundays from the total count of days between your selected start and end dates. This means only Mondays through Fridays are considered in the calculation, providing a count of the total working days in the specified date range.

Count End Day Explained

The "Count End Day" feature enables precise duration calculations by including the last day in your date range. This is vital for projects or deadlines, ensuring every workday counts, especially when weekends are excluded. For instance, a week-long project starting and ending on a Monday encompasses 6 full workdays with this option, offering a more accurate timeline for planning.
