What does this calculator do?
This is a simple day counter: it tells you the total number of days between a start date and an end date, with no year/month/day breakdown — just the single number most people are looking for when counting down to (or up from) a date.
How the calculation works
The calculator finds the exact number of calendar days between the two dates you choose, accounting for different month lengths and leap years automatically.
Worked example
From 1 January 2024 to 8 January 2024 is exactly 7 days — or 1 full week.
Understanding your result
The total is a straightforward day count between the two calendar dates. Total weeks is that day count divided by 7 and rounded down to a whole number.
Common uses
People use this to count down to a wedding, exam, trip or deadline, check how many days a rental or subscription period covers, or work out how many days have passed since an event.
Important notes
For a full years/months/days breakdown instead of just a day count, use the Date Difference Calculator.
