Google never shows you when a review was posted. It shows "3 months ago", and Business Profile Manager is no better, it shows "42 weeks ago" even on a listing you own.
If you have one review to date, paste its link into the free date finder. If you need all of them, you can export every review on any Google listing with the exact date and time on each.
Find the exact date of a Google review, free
Paste the link to the review, get the date and the time it was posted. That's the whole thing.
Open the review on Google and copy its link.
Paste it into the Google review date finder.
Read the date.
You get a second line when the review has been edited, with the date and time of the edit, as in the example above. That's often the more useful of the two. A review that was 5 stars in March and is 1 star now tells a different story to the one it appears to tell.
You also get the reviewer's name, the rating, the text and the business it was left on, and the result sits on its own link, so you can send it to someone. No account, no email, no card.
There's a limit of 5 a day. It's a free tool for the times you have one review to figure out.
Get every date at once, on any listing
When you need more than a handful, you stop looking them up one by one. You add the listing and every review arrives with the date and time it was posted, and the date of your reply.
The listing doesn't have to be yours. You don't connect a Google account, you don't need to be an owner or a manager, and you don't ask anyone for access. That covers most of the times this actually comes up:
A competitor's listing, when you want to know how fast they're collecting reviews.
A review in a dispute, when the date is the fact everything turns on.
A business you're doing diligence on, where the ratings matter and the access doesn't exist.
A client who never sent the login, or a location whose access left with the last manager.
The dates don't arrive on their own either. Reviews get tagged as they come in, and the tags run back across every review you already have, not just the new ones. Reviews in other languages get detected and translated. And the AI reads each review for the names in it, so a review that says "Marco was great" gets attributed to Marco, with only the confirmed matches written down.
Then you export the lot to a spreadsheet, with the columns you want in the order you want them. That part is covered in how to export Google reviews to Excel.
Reviewflowz gives you every review on any Google listing with the date and time it was posted, tagged, translated, and attributed to the staff named in it. The free date finder above stops at 5 a day, and Business Profile Manager shows you "42 weeks ago" even on a listing you own, so neither one ends with a dated file you can work from. Plans start at $45 per location per month, and you can point it at a listing you have no access to. Here is what a Google review export contains.
Reviews you wrote, or reviews you received
Two different things live under "my Google reviews" and it's easy to go looking for the wrong one.
Reviews customers left on your business belong to the listing. That's what this article is about, and it's what the date finder reads when you paste a review link.
Reviews you wrote about other businesses, as a person on Google Maps, belong to your Google account instead. You'll find them under Your contributions in Maps, and Google dates those the same way it dates everything else, so you get "3 months ago" there too.
