About this tool
Pick a start date and an end date and this calculator works out the gap between them. It counts the absolute number of days, so the order of the dates does not matter, then divides by 7 for weeks and by 30.44 (the average month length) for an approximate month count.
Frequently asked questions
Does the order of the dates matter?
No. The calculator uses the absolute difference, so swapping the two dates gives the same result.
Why is the month figure approximate?
Months have different lengths, so the result divides the day count by 30.44, the average number of days in a month, rather than counting calendar months.
