Does it count the first day?

No. Like most date-difference tools, we count the number of day boundaries crossed — from Jan 1 to Jan 11 is 10 days, not 11.

Yes. In "Add / subtract" mode, enter a negative number to subtract.

Date Difference & Arithmetic

Count the days between two dates, or add/subtract days from a date — in BS or AD.

Figure out exactly how many days (and weeks, months, years) lie between two dates — in either calendar. Switch mode to add or subtract a number of days from a starting date and get the destination date in both calendars.
