Time Travel discussion

Another person on the main "What's the name of that book?" group is trying to find out the name of a time travel story he/she has read. This one is a YA novel. Any of you can identify this one?

i read a book when i was in middle school about a teenager that accidentally traveled back in time while cleaning out an attic or garage. they went back to the 1940s or 1950s i think. i know that it took place during winter, maybe around christmas, and the teen runs into their teenage parents. i think when they first traveled to the past, other teens were ice skating. i also remember that in the past world the character mentioned going to catholic mass in the only catholic church in town. in the "time travel" world the teen was gone for a few weeks and was worried that their family in their world would be worried, and when they finally found their way back home, they had actually only been gone for a couple hours and no one noticed. i cant remember what triggered the traveling, i think it was an old picture or artifact they found while cleaning. i know the book was written before 2000. im thinking between 1960 and 1995 maybe. the book wasnt that thick and in paperback form. i just remember that as a 13 or 14 year old i found this book fascinating, and checked it out in the middle school library and would love to experience it again. so if anyone has any suggestions, that would be greatly appreciated. thank you.

no luck here, Huh Tej?

Looks like they got it back in June. https://www.goodreads.com/topic/show/...
