About this tool
How many days until the deadline? How long between two events? Pick two dates and get the total days, the weeks-and-days breakdown, the years/months/days difference and the number of weekdays (Monday–Friday) in between.
The weekday count is the sleeper feature: project timelines, notice periods and delivery estimates usually run on working days, not calendar days. Dates can be in either order — the calculator sorts them automatically.
How to use
- Pick a start date and an end date.
- Read total days, weeks, Y/M/D and weekday counts instantly.
Frequently asked questions
The count is exclusive of the end date — from Jan 1 to Jan 3 is 2 days. Add 1 if your use case counts both endpoints.
Yes, all date math uses the real calendar, so February 29 is counted correctly.
No — it excludes Saturdays and Sundays only, since holidays vary by country. Subtract your local holidays from the result.
