I can’t tell the exact date/time from the photo itself. That information would be stored in the image’s metadata (EXIF), and it may have been stripped.

How to check:

• Windows: right-click the image > Properties > Details > Date taken.
• macOS: open in Preview > Tools > Show Inspector > (i) > EXIF DateTimeOriginal.
• iPhone/Android: in Photos/Gallery, open the image and view its details/date.
• If you want, you can use a tool like ExifTool: exiftool yourimage.jpg to see DateTimeOriginal.

If there’s no metadata, or it was removed, the exact date/time can’t be determined from the image alone. If you share the file, I can help look for any visible clues.
