6 months ago

The date and what lies in between

“Today” is your device’s date, so the answer is right in your time zone. The page itself was generated on the date in the caption; your browser recounts the table when it opens. Counting back works the same way: yesterday is the first day, and the date shown is the last.

How 6 months are counted

Months are counted by the calendar: the answer is the same day number six months earlier. The number of days in between depends on the months — from October 7, 2026 it is 183 days — and the weekday is different. If that day does not exist in the earlier month, the answer is that month’s last day.

6 months ago or 180 days ago?

Eligibility rules that ask about “the last six months” usually mean the calendar months; rules written in days count exactly.

Common six-month look-backs

• Eligibility and history checks: “in the past six months” starts on the date shown; enter it in the days between dates calculator to count the days exactly.
• Statements and renewals: many accounts look back six months; check whether the start date counts.
• Reviews and check-ups: a six-month review covers about 26 weeks.

Checking the date by hand

Keep the day number and move the month back by 6: from October 7 that gives April 7 of the same year. If the target month is shorter than the start month — counting from the 31st, for example — take its last day instead, the way spreadsheets and most contracts do. The number of days in between is not fixed; the table above shows it for today’s date, together with the weekdays and holidays in the span, which matters when a deadline must land on a business day.

To count forward, set any period in the date calculator. For a 90-day look-back, see 90 days ago; to convert weeks to years, weeks to years.
