How to tell when a photo was taken
A photo's capture time is stored inside the file, in an EXIF field called DateTimeOriginal. You can read it with a metadata viewer or by checking the photo on ChronoVerify. Because that field can be edited or stripped, treat it as a strong lead, not absolute proof.
Where the date is stored
Most cameras and phones record the moment of capture in the photo's EXIF metadata, in a field named DateTimeOriginal, alongside the device make and model and sometimes GPS coordinates. This lives inside the image file itself.
That is different from the "date modified" your computer or phone shows in a file's properties. The modified date is set by the operating system and changes whenever the file is copied, downloaded, or edited, so it is not a reliable record of when the picture was actually taken.
Three ways to check the capture time
- Your device's file info. Phones and computers show a "Date taken" in a photo's details or properties. It is quick, but some viewers fall back to the file date when the original is missing, so it can mislead.
- A metadata viewer. Free EXIF viewers read the embedded data and show the capture date, the camera, and the settings.
- ChronoVerify. Upload or paste a photo and it returns the capture time, the device, and a plain-language verdict, plus whether the metadata is internally consistent and whether any signed Content Credentials are present.
Why a photo sometimes has no date
A missing capture date is common and is not evidence that an image is fake. The usual reasons:
- Screenshots carry no capture EXIF, because nothing photographed them.
- Social and messaging apps often strip metadata when you upload or download, to protect privacy and save space. A photo saved from a social feed or sent through some chat apps usually arrives with the date removed.
- Re-exporting or editing can drop or rewrite the field.
How far can you trust the date?
An EXIF timestamp is a claim made by the file, not a guarantee. It can be changed with free tools, so on its own it is a lead. Stronger confidence comes from corroboration:
- Content Credentials (the C2PA standard) are cryptographically signed, so a recorded time and edit history cannot be altered without breaking the signature. See our guide to Content Credentials.
- Internal consistency. Does the device, GPS, and timestamp agree with each other? ChronoVerify reports consistency and flags contradictions, without claiming an embedded time is true.
- Outside evidence. The position of the sun, weather, or a known event can confirm or contradict a claimed time.

Does every photo have a capture date?
No. Cameras and phones write one into the EXIF metadata, but screenshots, edited exports, and images stripped by social platforms often do not carry a capture date.
Why does my photo say "no capture date"?
The capture field was most likely removed when the photo was uploaded, downloaded, or re-saved. Many apps strip metadata for privacy and size. This is common and is not a sign of tampering.
Can a photo's date be faked?
Yes. EXIF timestamps can be edited with free tools, so treat a date as a lead, not proof, and corroborate it with signed Content Credentials, GPS, or other evidence.
Is "date modified" the same as when a photo was taken?
No. "Date modified" is set by your operating system and changes when a file is copied or edited. The capture time lives inside the photo's EXIF metadata.
