When was this website last updated?
Type a website address. Get every dated clue we can read: the Last-Modified header, sitemap dates, the footer copyright year, dates on the page and the newest WordPress post, with an estimate of when it was last touched. Free, no account.
Example: a sample plumber's page we wrote for this demo (smithplumbing.example is not a real site). Type any website above for a live check.
Appears stale since 14 Jun 2021 (5.4 years ago).

| Evidence | Date | What it means |
|---|---|---|
| Last-Modified header | none | Not sent. |
| Sitemap lastmod | 14 Jun 2021 | Newest of 2 lastmod dates in https://smithplumbing.example/wp-sitemap.xml. |
| Newest WordPress post | 14 Jun 2021 | From the site's WordPress REST API (/wp-json/wp/v2/posts). |
| Date on the page | 30 May 2021 | From the newest date written on the page. |
| Copyright year | none | The footer says © 2021. |
An estimate, not a fact: the newest dated clue we could read. A site can be edited without changing any date we see, and some systems update sitemap dates on their own.
How we estimate the last update
No website publishes a reliable "last edited" date, so we collect every dated clue from the page and the files around it, then take the newest one we trust:
- Last-Modified header: the server's own date for the page. Many servers stamp every response with the current time; when it matches our request time we show it but do not count it.
- Sitemap lastmod: the newest date in the sitemap listed in robots.txt, or in /sitemap.xml, /sitemap_index.xml or /wp-sitemap.xml.
- Newest WordPress post: on WordPress sites, the date of the newest post from the public REST API (/wp-json/wp/v2/posts).
- Dates on the page: published and modified dates in meta tags and structured data, <time> tags and dates written in the text.
- Copyright year: shown as a clue, never counted. Many sites print the current year with a script, and others forget to change it for years.
When the newest trusted date is more than a year old the site "appears stale". The Internet Archive's Wayback Machine is another place to see how a site has changed.

Questions
Check the Last-Modified header, the sitemap's lastmod dates, dates on the page and, on WordPress, the newest post. This tool reads all of them and shows each one.
Only a weak one. Some sites update it automatically every January and others never change it, so it is shown but not counted.
Many servers build pages on request and stamp them with the current time. That date is not an edit date, so we do not count it.
No. Nothing you type is saved.
