Why does my camera not hold the date and time?

@darla this is common once the RTC (real time clock) battery is depleted. your camera will not remember the time and date without this battery. Changing it by using this guide should resolve this issue.

Had the same problem with my Canon Powershot SX20 IS. Found this little battery compartment that holds the CR1220 on the bottom of the camera inside where the main batteries are installed. Just open the bottom battery compartment and you will see the small little part you need to slide off. You may need a small flathead screwdriver. Hope this helps someone else out there.

Try changing the tiny battery on the left side, on the top, pry open w/ your fingernail and replace this. I found this info doing a search online mine said CR-1220, its like a button battery, hope this works for you!

"I happen to have this exact same model camera and the same problem! To think, I only searched for Canon camera date reset in Google and it brought me right here!

It does appear the problem is the CR1220 button battery needs to be replaced. I think these can be found at most drug stores."

The date /time battery compartment is right beside the 3rd AA battery in the camera. It says CR1220 - that is the size of the tiny battery that goes in there. Hope this helps.

"I bought the battery t london drugs with tax like 10 bucks they said camera was older but they still caried that brand battery no problm in getting them,

and when i chnged it my time and date stayed set after i shut it off then on again,

problem solved"
