Frequently Asked Questions
What can I calculate with dates?
Our Date Calculator handles: days between two dates, add/subtract time periods (X days/weeks/months/years from a date), business days only (excluding weekends), and countdown to/from specific dates. Perfect for project planning, pregnancy due dates, and deadlines.
How do leap years affect date calculations?
Leap years (divisible by 4, except centuries not divisible by 400) add an extra day (Feb 29). Our calculator automatically accounts for leap years, so adding 1 year to Feb 29, 2024 correctly gives Feb 28, 2025 (or Mar 1, 2025 depending on your preference).
Can I calculate working days only?
Yes! Enable 'business days' mode to exclude weekends (Saturday/Sunday). You can also exclude specific holidays. This is essential for project timelines, delivery estimates, and contractual deadlines.
