Days between two dates
Pick a start and end date to get the exact number of days, plus the same gap in weeks, months and years, and the number of working days (Monday to Friday). Choose "inclusive" when both days count — leave days, notice periods and hotel nights are usually counted that way; age and "days since" are not.
Add or subtract days from a date
Switch to the second tab to find the date 30, 90 or 180 days from today — handy for cheque validity (3 months), FD maturity, passport/visa validity, warranty end dates, EMI due dates, or the last date to apply when a notice says "within 21 days". Adding working days skips weekends.
