Features of Our Tool
Our calculator provides the total number of days, breakdown into years/months/days, number of complete weeks, as well as the distinction between weekdays (Monday-Friday) and weekend days (Saturday-Sunday).
Frequently Asked Questions
No, our calculator counts calendar days. Holidays are counted as normal days. For an accurate count of working days, you'll need to manually subtract the holidays in your country.
Weekdays correspond to Monday through Friday inclusive. Saturdays and Sundays are counted separately as weekend days. This method is standard but may vary depending on conventions in your country or industry.
To calculate your age in days, enter your birth date as the start date and today's date as the end date. The calculator will give you the exact number of days since your birth, along with the breakdown into years, months and days.
Weeks are displayed with decimals because the interval between two dates rarely contains an exact number of complete weeks. For example, 10 days = 1.43 weeks (10 ÷ 7). Only complete 7-day weeks are counted as whole numbers.
