I just finished updating the DPS calendar for next school year.
This year they actually released it at a reasonable time, and didn't wait until well into February (after most summer camps require a deposit) to let us know when school would start.
I do this each year for myself, not wanting to refer to the ridiculously obtuse official calendar. (Do green-and-black checkerboards mean early release and blue octagons mean assessment day, or is it the other way around?) Last year I figured it could help a lot of other parents, so that's why I post it here on my blog. If there's something I can do to make it more useful, please let me know.
