How to use the 180 Days From Today
Read the answer: the date 180 days from today, with its weekday, is the large result at the top.
Change the start date to count 180 days from a sale date, an entry date, a policy date or any other event.
Pick “Days before” to get the date 180 days ago instead.
Tick “Count the start date as day 1” if your rule or challenge counts the first day.
Check the business-day lines, calendar and milestone table, and download the table as CSV if you need it.
How to find 180 days from a date
Add 180 calendar days to the start date, which counts as day 0. To check by hand, finish the current month and then step through the following months. From January 15, 2026: 16 days for the rest of January, 28 days for February, 31 days for March, 30 days for April, 31 days for May, 30 days for June, and the remaining 14 land on July 14, 2026.
180 days is 25 weeks and 5 days, a little under half a year (180 ÷ 365 ≈ 0.49). That is why the answer usually lands a few days before the same date six months on, and two weekdays earlier than the start weekday.
180 days after the 1st of each month
For a common (non-leap) year. Any span that includes February 29 ends one day earlier than shown.

Averages and pro-rating
Rolling windows: rules such as the Schengen 90/180-day limit look back 180 days from each day of a stay, so use “Days before” from the day you are checking.
Property exchanges: a like-kind exchange must close within 180 days of selling the old property, counting from the same day as the 45-day identification window.
Filing limits: some complaint and claim deadlines are 180 days; when the last day is a weekend or holiday, check whether your rule extends it to the next business day.
Frequently asked questions
What is the date 180 days from today?
It is shown at the top of the results, based on your device's date. The calculator adds 180 calendar days, weekends and holidays included, with today as day 0.
Is 180 days 6 months?
Not exactly. Six calendar months hold 181 to 184 days, so 180 days usually ends one to four days before the same date six months later. From January 1 it reaches June 30 in a common year; from March 1 it reaches August 28.
What weekday is 180 days from today?
180 days is 25 weeks and 5 days, so the weekday moves five places forward, which is the same as two places back: 180 days from a Monday is a Saturday, and from a Wednesday it is a Monday.
How many business days are in 180 days?
128 to 130 weekdays: 25 full weeks give 125, and the 5 extra days add 3 to 5 more. A half-year span usually also contains four to six federal holidays, which lower the count further.
How do I check the Schengen 90/180-day rule?
Short stays in the Schengen area are limited to 90 days in any rolling 180-day period. Choose “Days before” with your planned exit date as the start to see where the 180-day window begins, then add up the days you spent inside it (entry and exit days both count). Use the official EU short-stay calculator for a definitive answer.
What deadlines use 180 days?
Examples include completing a Section 1031 like-kind exchange (180 days after the sale, or the tax return due date if earlier) and filing a discrimination charge with the US EEOC (180 calendar days, extended to 300 in many states). Always confirm the exact rule that applies to you.
How long is 180 business days?
180 working days is 36 working weeks, which is 252 calendar days (about 8 months and a week) from a weekday start, plus one day for each holiday in between.
