How Harford calls a snow day
3 built in snow days
On the 2026 to 2027 calendar, listed as “potential inclement weather makeup days”.
“Three days during the school year—March 1, June 1, and April 12, 2027—have been set aside as potential inclement weather makeup days (in that order).”Source
Virtual learning days
Harford has virtual learning days in its winter plan.
“Making these changes allows HCPS to remain eligible to request a calendar waiver from the state, if needed, and ensures the school system is able to consider virtual instruction as an option for inclement weather.”Source
Making up a lost day
Used in order March 1, June 1, then April 12; unused days stay closed.
“*If no weather-related school closures occur before these dates, schools and offices will be closed on those days.”Source

How Maryland counts a lost day
Maryland requires at least 180 school days and 1,080 hours within 10 months, with days of at least 3 hours. On a county board's application showing it tried to comply, the State Board may shorten the year when severe weather or a disaster prevented normal attendance, without cutting state or local funding.
