If you have a kid in Somerville public schools, I made a calendar file for all of the 2026-27 holidays (except for winter and spring breaks): https://lab.brainonfire.net/calendars/Somerville-school-holiday-SY26-27.ics (It would be nice to have one with those, plus early-release days, but the tiny tool I wrote only supports full-day events. That's fine, now there's less to manually enter.) #SomervilleMA
