About this calculator
The difference counter measures whole calendar days between two dates, ignoring the time of day, and breaks the result into weeks plus a weekday count (Monday to Friday). Public holidays vary by country and are not excluded — for cross-border deadlines, subtract local holidays yourself or check the destination country's calendar.
Is the end date included?
No — the count is the number of midnights between the two dates, the same convention airlines, banks and spreadsheets use. From 1 Jan to 3 Jan is 2 days.
Does daylight saving affect the count?
No. Calculations run on calendar dates, not elapsed hours, so 23- and 25-hour DST days still count as one day each.
