DS didn't go to 1st grade at the Waldorf (started mid-way through 2nd) but the 1st graders at his school (in the Netherlands) go 8:20 AM to 1:00 PM every day except Tuesdays (I think) when they go for a normal day -- til 2:45 PM.
In 2nd Grade they go 8:20 AM-1:00 PM Mon., Wed., Fri. and 8:20 AM- 2:45 PM Tues and Thurs.
Now, in 3rd grade, they go 8:20 AM- 2:45 PM every day except Wed., which is early dismissal for the whole school at 1:00 PM.
Basically, they work their way up to "normal" school hours and ease into it so that by the time they're in 3rd grade, they're going full days except for Wed., which is a short day national-wide for all schools.
