Snapchat Memories Saved With the Wrong Date? Why, and How to Fix It
You did everything right. You requested your export, waited for the email, downloaded the ZIP, moved the files to your phone. And now ten years of summers, birthdays and 2 a.m. car rides are all filed under one afternoon in October 2026.
This isn't a bug you can retry your way out of, and it isn't something you did wrong. It's how the export is built. Here is exactly why it happens, where Snapchat keeps the real dates, and three ways to get them back — from free and slow to one tap.
Why your Snapchat Memories show the wrong date
Every photo your phone's camera takes carries a small block of hidden data called EXIF. It records, among other things, the moment the picture was taken (DateTimeOriginal) and, if location was on, where. Google Photos, your phone's gallery and every photo app on a computer sort your library by that field.
The files in a Snapchat export don't have it. Open one in any EXIF viewer and the capture date and GPS fields are simply empty. So your gallery does what it's designed to do when a photo has no capture date: it uses the date of the file itself. And the file was created the day you downloaded or unzipped your export.
That's the whole mechanism. Three thousand Memories, one date.
Two things make it worse:
- Captions and stickers are separate files. A captioned Snap arrives as two files: the clean photo or video (
…-main.jpg) and a transparent image holding your text and stickers (…-overlay.png). Copy everything to your gallery and you get the photo without its caption, plus a ghost of the caption on its own. More on this in our export troubleshooting guide. - Videos are hit too. MP4 files have their own date fields, and they come out empty in the same way. Videos land at the top of your timeline, next to the photos.
Where Snapchat keeps the real date
The good news: Snapchat doesn't throw the information away. It's in the export, just not where your gallery looks.
In the file name. Recent exports name each file after the day it was saved, like this:
memories/2019-07-14_A6BDBF7C-B31E-6CE2-19D3-A48C8F169EC0-main.jpg
memories/2019-07-14_A6BDBF7C-B31E-6CE2-19D3-A48C8F169EC0-overlay.png
That gives you the day, but not the time and not the place.
In memories_history.json. Inside the export's json folder, this file lists every Memory with its full date and time and, when location was on, its coordinates:
{
"Date": "2019-07-14 19:42:07 UTC",
"Media Type": "Image",
"Location": "Latitude, Longitude: 50.8503, 4.3517"
}
Two details matter if you fix the dates yourself:
- The time is in UTC, not your local time. A Snap from 11 p.m. in New York is stored as 3 a.m. the next day. A tool that writes the UTC time as if it were local will push your late-night Memories onto the wrong day.
- "0.0, 0.0" means no location, not a place. Memories saved with location off are listed at latitude 0, longitude 0. Write that into a photo and your map app pins it in the Gulf of Guinea.
Three ways to fix the dates
1. By hand, in your gallery app (free, for a handful)
Google Photos and most gallery apps let you edit a photo's date. Look up the real date in the file name, open the photo, edit date and time, save.
It works, and it's free. It also takes about a minute per photo, it doesn't fix the location, and it does nothing for the caption sitting in a separate file. Fine for your twenty favourite Snaps. Not for three thousand.
2. With a script on a computer (free, technical)
Open-source scripts on GitHub read memories_history.json and write each date back into the matching file, often with the location too. If you're comfortable installing a tool and running commands in a terminal, this is the free way to fix a whole archive.
Check three things before you trust one with your memories: that it handles the UTC offset, that it skips "0.0, 0.0" locations, and that it works on copies, not your only originals. Then you still have to get thousands of fixed files from the computer back onto your phone.
3. With Still Mine, on your phone (free to look, €4.99 to keep)
This is the app we built for exactly this problem, so take the recommendation with that in mind. You open the ZIP exactly as Snapchat sent it, on your iPhone or Android phone. Still Mine reads the dates and places from the export and shows your whole archive as a timeline, year by year. Looking is free.
If you want to keep it, a one-time €4.99 saves every Memory to your gallery at full resolution, in a Still Mine album. Each file has its original date and place written back in, and its caption and stickers put back on the picture. Nothing is uploaded: the whole thing happens on your phone. No account, no subscription.
