Why dates seem to change after a Google Takeout export
A photo may display different dates depending on where you look at it. The date shown for a file on your computer, a date embedded in the media and a date stored in a Takeout JSON file do not always describe the same event.

KEY POINTS
What to know before organizing your files
- The date shown by your file manager may reflect when a file was downloaded or extracted.
- A date embedded in the media and a date stored in a JSON file are separate sources.
- PhotosClaires counts photoTakenTime first and uses creationTime only as a fallback.
- The scan writes no date to your files and never guesses a missing value.
START WITH THE SOURCE
Three families of dates that should not be confused
1. The file date on your computer
“Created” or “Modified” is file-system information. It may refer to a recent copy, download or extraction. On its own, it does not prove when the photo was taken.
2. The date embedded in the media
A photo or video may contain its own metadata. Google explains that the operating system may assign a new timestamp to the downloaded file, while the original timestamp remains preserved in the metadata embedded in the media when it is present there.
3. The date in the sidecar JSON file
Takeout may also provide information in a nearby JSON file. This source is separate from the media: a date being present in the JSON file does not mean that it is embedded in the photo or video file.

TWO FIELDS, TWO LEVELS
photoTakenTime and creationTime do not tell the same story
In a recognized media JSON file, PhotosClaires first looks for a valid value in photoTakenTime.timestamp. The report classifies it as an available photo-taken date.
If that value is missing, the scan may count a valid creationTime.timestamp value as a fallback date. This separation is deliberate: a creation date is not, by itself, proof of when a photo was taken.
To understand how a JSON file is matched to its media, read the guide to Google Takeout JSON files.
READ THE COUNTS
What the PhotosClaires report lets you distinguish
- Available photo-taken dates: media matched to a JSON file containing a valid
photoTakenTime. - Creation dates available as a fallback: media with no recognized photo-taken date but with a valid
creationTime. - Orphaned JSON files: metadata files for which no reliable media match was found.
- Ambiguous matches: several media files are equally plausible candidates, so no date is assigned arbitrarily.
These numbers provide a snapshot. They help you assess the scale of any work that may be needed in another tool, but they do not guarantee that a date is historically accurate.
VERIFY BEFORE YOU ACT
A cautious method for reviewing inconsistent dates
- Keep the original export untouched
Always work on a copy if you later use software that rewrites metadata.
- Diagnose the complete folder
Media and their JSON files should remain together to maximise reliable matches.
- Compare all three sources
Review the file date, embedded metadata and JSON file without assuming that they are equivalent.
- Check representative cases
Choose several years, formats and devices before applying a rule to your entire photo library.
- Handle exceptions separately
A missing or contradictory date must remain uncertain until reliable evidence resolves it.
FREQUENTLY ASKED QUESTIONS
Questions about Google Takeout dates
Why do all my photos seem to be dated on the day I downloaded them?
Your file manager may be showing the file date created during download or extraction. That is not necessarily the capture date.
Is a photoTakenTime date automatically accurate?
No. It is an available photo-taken date in the associated JSON file, but checking a sample and any warnings in the report remains prudent.
What does creationTime mean in the scan report?
PhotosClaires counts it only as a fallback when no valid photoTakenTime is available in the recognized JSON file. It is not presented as conclusive proof of capture.
Does PhotosClaires restore dates in my photos?
No. It diagnoses the dates available locally in your browser. It does not modify media, JSON files or file-system timestamps.
CHECK BEFORE YOU ACT
Start by taking stock of your export
PhotosClaires checks the folder you have already extracted, locally in your browser. It is free, requires no account and uploads nothing. No file is renamed, corrected, moved or deleted.
