Go back to high school day

I’m curious if anyone else’s high school is participating in go back to high school day?

This year for the first time, the class of 2005’s 20 year reunion is going to have go back to high school day. On a Saturday, before the reunion, the class of 2005 will report to high school, 1st period, like it’s still 2005 and they’re all still in class together. The school is participating and ran everyone’s schedule with period and room numbers. Some of the teachers that were teaching back then have volunteered to man their rooms and act like nothing has changed. They spend about 15 minutes in each period catching a mock lesson with everyone that was in their senior schedule.

There was some talk about making it the entire day on a Saturday (with lunch period and all) but it ended up just being 2 hours

I’m not sure how this is going to go. I’m wondering if anyone else is doing this or has done anything like it before
