How do you calculate 180 days from today?
180 days are counted in calendar days, with today as day 0. The calculator adds 180 days to the start date (today unless you change it), or subtracts it in “before” mode, using plain Gregorian calendar dates with no time zone. Working days are weekdays that are not US federal holidays, counted after the start date up to and including the end date. Federal holidays use the observed date, so a Saturday holiday is observed on Friday and a Sunday holiday on Monday. If the result falls on a weekend or a federal holiday, the next working day is shown too. Employer, state and bank holidays are not included.
For example, 180 days after Monday, February 15, 2027: 180 days is 25 weeks and 5 days, so the weekday moves 5 days and the date is Saturday, August 14, 2027. Of the 180 days after the start, 129 are weekdays and 3 of those weekdays are federal holidays, which leaves 126 working days. The dates are made up for the example; yours start from today or from the date you enter.
