From the start date, when will these milestones be reached?
To find days between dates: subtract the earlier date from the later date. Our calculator instantly shows the difference in days, weeks, months, and years. To add days to a date: select start date and enter number of days to add. For business days, exclude weekends and optionally holidays. Example: January 1, 2025 to December 31, 2025 = 364 days = 52 weeks.
Enter both dates and the calculator will show the difference in days, weeks, months, and years. It also calculates workdays (excluding weekends) and weekend days separately.
Yes! The calculator uses proper date math that accounts for leap years, varying month lengths (28-31 days), and all calendar irregularities. February 29th is included in calculations when applicable.
Workdays are Monday through Friday. The calculator excludes Saturdays and Sundays. Note that public holidays are NOT excluded as they vary by country and region.
Switch to "Add Days to Date" mode. Enter a start date and the number of days to add. The calculator will show the resulting date. You can also subtract days to find past dates.
Months have different lengths (28-31 days), so 30 days doesn't always equal 1 month. The calculator counts actual calendar months, giving more accurate results for date planning.
