Days since = today's date minus the date you enter, counted as whole calendar days.
Frequently Asked Questions
How does this calculator count days since a date?
It counts the exact number of calendar days between the date you enter and today, using today's actual date each time the page is loaded.
Does it include both the start and end day?
No — it counts the whole days that have passed between the two dates, the same way you'd count nights on a trip rather than counting both the departure and return day.
What if I enter a future date by mistake?
The calculator still works — it shows how many days until that date instead, since a future date has a negative days-since value.
