Today is day 0; count 180 full days back. This is the main answer above.

Some rules count today as the first of the 180 days, landing one day later.
Is a Date Within the Last 180 Days?
Pick the date on your receipt, statement, or record and see exactly how many days back it falls — and whether it is still inside a 180-day window.

What 180 Days Ago Means
The half-year lookback
One hundred eighty days ago is the standard "last six months" date. Banks ask for up to six months of statements, cheques in many countries go stale after six months, visa rules measure presence across 180-day windows, and plenty of eligibility rules are written as "within the last 180 days."
Six calendar months and 180 days differ by one to four days depending on where the span falls in the year, so when a rule is written in days — as most formal ones are — the date above is the one that counts.
Common Reasons to Look Back 180 Days
- Assembling six months of statements or payslips for an application
- Checking whether a cheque or document older than six months has gone stale
- Anchoring the 180-day window used by rolling visa rules
- Verifying "within the last 180 days" eligibility conditions
Documents Age Out Around the Six-Month Mark
A surprising number of documents quietly expire near 180 days. In several countries banks may refuse cheques presented more than six months after their date; lenders typically want statements and payslips no older than three to six months; and many certificates and clearances are only accepted for six months from issue.
The pattern is worth internalizing: if a document is dated earlier than the date shown above, assume a bank, lender, or agency may treat it as stale and check before relying on it.
- Cheques are commonly treated as stale after six months
- Lenders want recent statements — often within 90–180 days
- Anything dated before the date above deserves a freshness check
How This Calculation Works
This page counts exactly 180 calendar days backwards from today — weekends and holidays included — using your local date, so the answer rolls forward at your local midnight. The calendar below marks every day in the lookback span so you can trace it against month boundaries. Planning forwards instead? See 180 days from today. If your rule counts working days only, use the business days calculator, and for arbitrary numbers or specific start dates, the main days calculator handles both directions.

Frequently Asked Questions
Count back 180 calendar days from today's local date, treating yesterday as 1 day ago — so today itself is day 0. Saturdays, Sundays, and public holidays are all included. Because the count starts from your local "today," the answer rolls forward at your local midnight.
Under the usual convention, no: today is day 0 and yesterday is day 1, which is the main answer shown on this page. Some rules count inclusively instead, treating today as day 1 — that reading lands one day later, and both dates are shown side by side above so you can match the wording of your rule.
Usually yes — "within the last 180 days" almost always means the window from that date through today, inclusive at both ends. The date shown above is the oldest date that still qualifies; anything earlier falls outside. Use the window checker on this page to test any specific date.
Yes. This page counts calendar days, so every day on the calendar is included. If your rule counts working days instead — "10 business days" is a different span than 10 calendar days — use the business days calculator.
