Count days between two dates
Frequently Asked Questions
How do I count the days between two dates?
Enter a start date and end date. The calculator subtracts the earlier date from the later and shows the total number of calendar days. From January 1 to March 15, 2025 = 73 days.
Is the count inclusive or exclusive of the end date?
By default, the count excludes the end date (the standard mathematical difference). Toggle "include end date" to add 1 day for inclusive counting. From Monday to Friday: exclusive = 4 days, inclusive = 5 days.
How many days until a specific holiday?
Enter today as the start date and the holiday as the end date. The calculator shows the exact number of days remaining. It also displays the result in weeks and days for easier comprehension.
Can I calculate days between dates in different years?
Yes. The calculator handles any date range, including across years and centuries. From December 25, 2024 to January 5, 2025 = 11 days. It correctly accounts for leap years in multi-year spans.
How do I calculate the number of weekdays between two dates?
For weekdays only (excluding Saturday and Sunday), use the Business Days Calculator. This tool counts all calendar days. The difference can be significant: 30 calendar days typically contains only 22 weekdays.
