Date calculators do calendar maths that is easy to get wrong by hand: how many days lie between two dates, how old someone is in years, months and days, or how many working days remain before a deadline. Months have different lengths and leap years add an extra day, so simple subtraction rarely gives the right answer.
TimePanel’s date tools work with real calendar dates. The Date Difference calculator gives the total days, weeks and business days between any two dates, with an option to include the end date. The Age Calculator shows an exact age, the total number of days lived and the date of the next birthday — including the correct handling of people born on 29 February. Every result explains itself, so you can check the numbers by hand.
Frequently Asked Questions
Do the date calculators handle leap years?
Yes. Calculations use real calendar dates, so 29 February and months of different lengths are counted exactly.
Are public holidays excluded from business days?
No. Business days count Monday to Friday only, because public holidays differ between countries and regions.
Which time zone is used for “today”?
Today is taken from your own time zone, so the result matches the date on your calendar.
