Frequently Asked Questions
How is the difference between two dates calculated?
We compute the calendar difference in years, months and days from the start date to the end date, then also show the total number of days, weeks and hours.
Does this include leap years?
Yes. JavaScript's Date object accounts for leap years automatically, so February 29 is handled correctly.
Can I use this to calculate notice period?
Yes — enter your last working day as the start date and the notice period end date to see exact days, weeks and months.
