June 17, 2027, on the district’s 2026 to 2027 calendar.

About 61.1 inches a winter at a NOAA weather station 3.4 miles away, averaged over 10 winters. Between December 1 and March 31 that brings 4.9 weekday mornings a year with 2 inches of new snow or more, and 2.6 with 4 inches or more.

21.8 inches on March 13, 2018, the largest single day at a NOAA weather station 3.4 miles away in 10 winters. The snowiest winter was 2017 to 2018, with 96.1 inches.

Worcester averages 2.6 weekday mornings a winter with 4 inches of new snow or more, more than 80 percent of the 291 Massachusetts districts with a station record.

It reads the National Weather Service forecast for Worcester through the night and the 5 to 8 am bus run, adds winter alerts and the Winter Storm Severity Index, and measures the snow against Worcester’s own big snow morning: 5.3 inches, the top tenth of snowy weekday mornings at a NOAA weather station 3.4 miles away.

Massachusetts requires a 185 day calendar, at least 180 days actually held, and 900 hours for elementary or 990 hours for secondary students. Every day lost through March 31 is made up with full rescheduled days; after March 31, days are made up until 180 or the scheduled 185th day, whichever comes first.
