What Date Was 180 Days Ago?
Subtract 180 days from today's date to get the exact result below -- the calculator uses your device's own clock, so it's live and correct right now, not just on the day this page happened to be generated.
Subtracting days from a date is a plain count backward on the calendar -- a day is always 24 hours and the count carries cleanly across month-start and year-start boundaries, with no rounding or ambiguity involved. 180 days is 25 weeks and 5 days -- it doesn't divide evenly by 7, so it isn't a whole number of weeks. Need a different offset, a different start date, or a unit other than days -- weeks, months or years? The add/subtract days calculator handles any combination.
Looking for the opposite direction instead -- what date it will be 180 days from now, rather than 180 days in the past? See 180 days from today.

Frequently Asked Questions
How is 180 days ago calculated?
Take today's date and count backward 180 calendar days, carrying across month-start and year-start boundaries the same way a physical calendar does in reverse -- there's no rounding or approximation involved. The calculator above does exactly this, live, using your device's own clock to get today's date, so the result you see is correct the moment you load the page rather than a stale answer baked in whenever this page happened to be generated.
Is this calendar days or business days?
Calendar days -- every day counts, including weekends and holidays. If what you actually need is working days only, skipping weekends and US federal holidays, use the business days calculator instead.
How many weeks ago is 180 days?
180 days is 25 weeks and 5 days -- it doesn't divide evenly by 7, so it isn't a whole number of weeks.
Why would the date shown here be different tomorrow?
Because "today" itself moves forward every day. This page always subtracts 180 days from whatever today's date is at the moment you load it, computed live in your browser -- it is never a fixed, pre-calculated answer, so it can't go stale between visits.
