The Simple Art of Counting Days 📅
Calculating the number of days between two dates seems simple, but it can be surprisingly tricky. You have to account for the different number of days in each month and, of course, leap years. This calculator automates the process, giving you accurate results for any time frame.
Calculating the Duration Between Two Dates
This is the most common use case. Whether you're tracking a project's length, counting down to a vacation, or determining how old something is, finding the duration is key. Our calculator determines the exact number of full days that have passed between the start and end dates.
Adding or Subtracting Days
Another frequent need is to find a future or past date based on a specific number of days. For example, "What is the date 90 days from today?" or "What was the date 30 business days ago?". This is critical for setting deadlines, understanding delivery times, or calculating expiration dates.
The "Weekdays Only" Difference
For many professional and business purposes, you're only interested in "business days" or "weekdays" (Monday to Friday). Calculating this manually is tedious. Our "Exclude weekends" option does the heavy lifting for you. It iterates through the date range and only counts the days that don't fall on a Saturday or Sunday, giving you a practical count for your project plans and business schedules.
Whether you need to know the total number of days for a personal countdown or the number of working days for a professional project, this versatile tool provides the answer instantly.
