Day Counter – Counts the number of days between two calendar ...

The Day Counter counts the number of days between two calendar dates. This Day Counter handles date and time calculations precisely, accounting for variable month lengths, leap years, and calendar rules automatically.

The formula behind this calculator: Counts calendar days between two dates, optionally including or excluding the end date. As a practical example: From June 1 to June 30 is 29 days, or 30 if the end date is included. All results are calculated instantly in your browser — no data is stored or transmitted.
