Days Between Dates Calculator

Use our calculator above to find the exact number of days between any two dates. Simply enter your start date and end date, and the calculator will show you the precise count. For example, if you want to know how many days are between January 1, 2024 and March 15, 2024, the calculator will show you the exact number.

Our calculator uses precise date arithmetic to determine the exact number of days between two dates. We count each day between the start and end dates, and you can choose whether to include or exclude the end date in the calculation. For example, between January 1 and January 3, there are 2 days if excluding the end date, or 3 days if including it.

Calendar days include every day (weekends and holidays), while working days exclude weekends and optionally holidays. For example, if you calculate the period from Monday to Friday, you get 5 calendar days but only 5 working days. If you calculate from Monday to the following Monday, you get 8 calendar days but only 5 working days (excluding the weekend).

Working days calculations count each day between the dates, excluding weekends (Saturdays and Sundays by default) and holidays if enabled. For example, if you're calculating working days between January 1 and January 10, the calculator will skip any weekends and holidays that fall within that period, giving you only the business days.

It depends on your specific needs. Including the end date counts it as a full day, while excluding it doesn't count it. For example, if you're calculating a project that ends on Friday, you might want to include Friday to count it as a working day. For age calculations or periods that end at midnight, you might want to exclude the end date.

This calculator is perfect for project timeline calculations, contract period durations, event planning timelines, vacation day calculations, business day counting, age calculations, and investment period tracking.

Our calculator is highly accurate and accounts for leap years, varying month lengths, and precise day counting. It provides exact day counts suitable for legal, business, and personal use.

Yes, you can enable holiday exclusion and select your country. The calculator will then skip official holidays when calculating working days. For example, if you're calculating working days in the US around Christmas, it will skip Christmas Day and New Year's Day automatically.
