My husband and I recently returned from 2 weeks in Portugal (yes, I took my new Nikon D 7500 that I so agonized over right before the trip. Took almost 4000 pictures many of which I am delighted). When we landed in Lisbon, I set the camera to the correct time zone. However, somehow I set it for the wrong month so now all those photos have dates on them from May 22-Jun 3 instead of the correct dates of Apr 22-May 3. Is there any way I can change those dates on my computer so they are correct? As it is, the pictures I am taking now, with the correct date fixed on the camera, are appearing smack dab in the middle of our trip pictures in the library section of Photo on our Mac. Thanks.

If you are handy with the command line, there is a free, powerful program called ExifTool that can perform this magic. And it can work on batches of files, so you don't have to change 4,000 images one at a time.

The easiest thing to do is to take all the Lisbon photos and place them in an album. Then when you want to look at them you bring up the album and they're all there, without other interfering photos. You don't have to change the date to do that.

If you do change the date, it will not affect the album.

Albums don't have to contain sequential photos. You can make albums for family members or family groups.

Use albums more than the full library.

That is true. I do have all the Lisbon photos in an album. But, I would still like all my photos to be in the correct sequence in the "library" if that is possible.

Thanks. I will have to check this out. Have you used this program?

I had much the same problem a few years ago when I shot all day with the wrong date-time on my camera after the battery had died and lost the proper date / time. This version of EXIF will update the relevant time- and date-stamps the image files:

EXIFTOOL "-AllDates+=5:10:2 10:48:0" *.jpg

(above adds 5years,10months,2days,10hours,48-minutes to the date-time of the files in DIR

So, if you just need to "remove" 1-month, try parameters like:

EXIFTOOL "-AllDates-=0:1:0 0:0:0" *.jpg

The command above acts on all *.jpg files in the folder / directory where the change is executed in a command window. Update to your file type / extension, if needed. The EXIFTOOL creates back-up "original" files that can be deleted after you're satisfied with update.

I extracted the pre / post dates from a file and highlighted the impacted fields for -1 month. The 'create date' is the value used by the operating system / digital database for sorting by create-date.

Create Date : 2020:01:01 00:00:22
Date/Time Original : 2020:01:01 00:00:22
File Access Date/Time : 2023:05:21 08:58:58-05:00

Sony Date Time : 2020:01:01 00:00:22
Sony Date Time 2 : 2020:01:01 05:00:22

Thanks Paul!
I copied and pasted that info to an ExifTool notes file!

Here's one problem with that approach: EXIFTool works on files in a folder/directory.

On the Mac, Photos stores the images somewhere but doesn't tell you where. In Finder, I can right click on an image file and select 'get info' which brings up a dialog with information that includes the path to the image file. In Photos, if I right-click and select 'get info' the resulting dialog has no information about where the image file is located.

I can right-click on an image in Photos and select 'edit in' something. If I edit in Photoshop, going to 'save as' will bring up a dialog that wants to save the file to a folder and you can see the name on that folder. Choosing adjacent photos taken on the same day, the folder appears to be constant. But although I have the name of the folder, I don't have the full path. An example of a folder name is

I suppose I could download all the photos from Photos to another folder, but if the dates get changed on the other folder, it's cumbersome to re-import them to Photos because it won't want to load duplicates.

Photos has some convenience factors, but I try to keep my photos somewhere else.

Longshadow Loc: Audubon, PA, United States

Haha - I'd change that folder name so fast the computer wouldn't know what hit it.....
Whatever I may download, from Facebook or wherever, I ALWAYS rename the file(s), to something useful.
Besides, why would one worry about a path on the UHH server, to which one probably cannot write.

The images didn't have spontaneous generation inside Photos. The Photo software (database) imported them from someplace. Update the images at 'someplace' before importing / exposing the files to Photos. It would be better to recognize (and correct) the date-time issue prior to needing to remove, update and re-import into Photos.

Right, but the OP's photos are in Photos now.

Very easy if you use Apple Photo. Open your Photo Library. Top row click on Image then click on Adjust Date and Time. Select all the photos in the same time sequence with incorrect time, and adjust first photo to correct time and you are done. ...... Correction: select images first, then go to Adjust Date & Time.

MaryFran Loc: Front Royal, VA

I am using Apple Photo. I have opened the photo library and clicked on the image. I see no "top row". I also see no "adjust date and time".

MaryFran Loc: Front Royal, VA

When I right click on the photo, all the choices given are get info, make key photo, show in all photos, rotate clockwise, revert to original, duplicate 1 photo, play slide show, share, create, add to, edit with , hide 1 photo and remove 1 photo from album. I don't know what this "top row" is you are mentioning.
