Tumblr shows posts as “5 hours ago” or “a year ago” instead of the actual date. Paste any public post URL to get the exact publish date and time.
We read the post's structured Schema.org metadata directly from the page — no Tumblr login required.
Tumblr only shows you 'X days ago'. We extract the precise publish date from the post's structured data — accurate to the second.
Both `blog.tumblr.com/post/...` and `tumblr.com/blog/...` URL formats. We auto-normalize whatever you paste.
Pulls the post's author handle, title, and a short summary so you can verify you've got the right post.
Each unique post URL is cached for 24 hours so we're not hitting Tumblr unnecessarily. Per-IP rate limits keep things polite.
Tumblr's web UI shows relative dates ('5 hours ago', '2 weeks ago') instead of exact timestamps. The exact date is in the post's HTML metadata but isn't displayed by default. This tool reads that metadata and shows it to you.
Three common reasons: (1) Citation and attribution — quoting a Tumblr post in writing or research. (2) Archiving — knowing when something was published before it disappears. (3) Fact-checking — verifying when a viral post was actually originally written, since reblogs make it hard to tell.
It returns the date of the post you paste — meaning the date that specific reblog was published, not the date of the original post. To get the original post's date, click through to the source on Tumblr and paste that URL instead.
Both work: `https://changes.tumblr.com/post/123456789` and `https://www.tumblr.com/changes/123456789`. The post ID alone is the unique identifier; titles and slugs are optional.
A few reasons: the blog hides itself from logged-out users, the post was deleted, or the blog uses a heavily customized theme that strips the standard metadata. Most public posts work fine.
