Do you have a pile of old photos and can’t quite figure out when a certain picture was taken?  Anyone who tries to date and organize photos has had this dilemma, whether you are a do-it-yourselfer or a professional photo organizer.

Recently we asked members of the Association of Personal Photo Organizers what tips and tricks they use to date enigmatic Photos. We think you will find their answers extremely helpful.


Photo Detective Tools

Before you get started it can help to have some tools handy…your photo detective bag of tricks as it were.

  • A good magnifying glass or jeweler’s loop (If the photo is already digitized, the zoom function will be your friend.)
  • Google or your favorite search engine
  • Books or websites about fashion, hairstyles, photo types (Check out the selection offered by Maureen Taylor, The Photo Detective.)
  • A family timeline of important dates and events


Photo Detective Tips

Here are some of photo detective tools that the APPO experts use on a regular basis.


Obvious Clues

If you get lucky, the back of the photo can give clues to location or date. If you are really lucky someone has written down identifying information (people, place, event, date). Congratulations, you have just won the photo detective jackpot!

In some cases, a developing date is printed on the back or in the border on the front. A word of caution – machine printed dates on photos are the date the print was developed, not the date the photo was taken.  One obvious example would be a Christmas photo dated January 1952 but was probably taken during Christmas of 1951. I have had clients reprint an old scan which then got mixed back into their print collection. The photo was obviously from the 1940s but the developing stamp on the back said May 2015.

Many photos from the 1950s have the developing date printed in the margin on the front of the print.

Sometimes the date taken is not so obvious. When we still used actual film in our cameras, many people did not get it developed right away.   When only 4 or 5 photos were taken at an event, often the film contained several events before it was developed.  Remember the date on the back is the date developed.

Some photos taken with digital cameras and then printed may have date stamps on the front of the printed (or digital) photo. Take this date with a grain of salt. Just like the blinking clock on a VCR, many people never correctly set the date on their camera.

Be careful. That date stamp may not be correct.


Physical Clues

Look at the size, shape, and paper of the photo itself. Major developers like Kodak have changed their style over the years and these can be a great clue to the era in which a photo was developed.

Here are some online resources that you can use to identify the age of a print by its type and paper among other characteristics.

Several physical clues point to a date of the 1950s for this photo – the deckled (scalloped) edges, the Kodak Velox paper and the fact that it came bound in a small spiral-bound book from the developer (hanging chad on the side).


Slides will also have a date stamped on the paper or plastic mount. But remember that this is the developing date, not the date the photo was taken.

Date stamps on slides vary by date, film type, and developer.


If your photos are in the original developing envelope, check it for dates. This will give you a time when the photo was developed. It may even have an address or phone number of your family member on it which could aid your search.

For professional photographs, research the photographer to find out when they were active.


Happy Birthday To You

Count the candles on a birthday cake.  Keep in mind that some families “add one for good luck” and some people have multiple birthday parties each year.

Counting candles on the cake can help. This one is a little confusing if you didn’t know that these two little girls always celebrated their birthdays together. Eight candles on the left for the girl on the left and five candles on the right.


Sandra Williams, Infinity Photo Solutions

“I (have) counted candles on a cake to determine the person’s age, used a magnifying app on my phone to read the name of the university on a diploma, and googled an obituary to find a date of birth.”


Car Hints

Look for a year on a license plate.

What is the make and model of the car? This can help pinpoint decades.

Study the state/province on the license plate and google images for license plates for those years

A little research on the type of car and the license plate could give us an approximate date for this family’s first car.


Kathy Stone, Calgary Photo Solutions

“I was looking at old photos online of Michigan Tech campus to see if the photos I was sorting were taken there and using a magnifying glass on old photos to see license plate and shape of the grill on the truck in different photos.”


What’s in the Background

Use a magnifying glass to look for anything in the background that may give clues to the date. Some ideas are:

Calendars in the photo will give you a general time frame to consider.

The calendar in the background leads us to the conclusion that this photo was taken in 1971.

Look at the headlines of newspapers or magazines in the photo, then google the headline.

A certain TV show or newscaster on a TV may help you narrow down a date.

Is that Walter Cronkite in the background? You could google a picture of him and guesstimate the time period.

Research dates of sporting events by the teams playing on the TV in the background.

Zoom in and look for any hand-written notes, such as the label on a cradle in a hospital nursery.


Laura Woolsey, Memory Forward

“If I had a nickel for every birthday candle I’ve counted! Kitchen calendars with just the month and day can help and I have used Google to find the year that it could have been.“


Location, Location, Location

In outdoor shots, look for house number or street address, to match with years lived in a location.

Look at the shape of a door, the finish on the house, the type of porch, the style of windows to match an unknown photo with a known photo or to fit into a known chronology.

Look for words or logos on advertising signs to pinpoint a location and/or date.

To date this photo, one could google Gulf gas pumps and logos to find the general time period. If you knew the location of this store, you could try to find out the dates the store was in business.


Indoor/outdoor seasonal decorations can give hints of the time of year.

Construction and restoration of major buildings and monuments can give you a time frame in which the photo was taken. Skylines with missing landmark skyscrapers could give hints to date. For example, New York City without the Twin Towers is either pre-1973 or post-2001.

When was Big Ben under restoration?


Cheryl DiFrank, My Memory File

“I’ve used a magnifying glass to read a few words of a newspaper headline on a desk and then googled the headline. I have also googled what football teams played each other on a certain date.”


Fashion Details

Hairstyles and clothing can help identify the approximate date of a photo. Maureen Taylor, The Photo Detective, has some great resources for dating your ancestor’s photos through their fashion.

Researching these gentlemen’s clothing and hats could give you a clue to the photo’s date.


Pay attention to details like bangs (Suzie got bangs in 3rd grade so photos with the bangs are probably 3rd or 4thgrade) or braces. They may not give you a specific date, but they may help your general chronology. These are good details to add to your family timeline.


What’s Going On

If the photo shows a public event (IndyCar race, State Fair, concert), google the names of the events then look for logos that match yours. That will usually help you find the year, if not the month and day too.


Mother Nature

Take note of blooming flowers or bare trees. This will give you an idea as to the time of year.


Debbie Wiener, Got Pix

“I’ve compared several pics of a child and aged them as before braces, with braces, straight teeth! Also, house pictures (can be dated) by sizes of the trees.”


Other Supporting Documents

If you have other supporting documents such as obituaries and funeral service bulletins, they can give dates of birth, places of residence, family members and other information that can help identify photos.

Birthday party invitations with a specific theme (like Spiderman or roller skating) can give you a date when paired with photos showing the same theme.


Of course, if you have a family member (or two) that you can ask about dates, locations, and stories, they may be your most valuable resource.
