SED posted this message on their website regarding the observance of the Juneteenth holiday:
General Construction Law §24 provides rules for holiday observance: Section 24 stipulates that any holiday that falls on a Sunday is observed on the Monday after. For example, Juneteenth falls on Sunday, June 19 in 2022, and will be observed on Monday the 20th. The law does not require that holidays falling on a Saturday are observed on a Friday. In 2021, June 19 falls on a Saturday, so districts are not obligated to close for this holiday.
The 2021 regents examination notice specifies that no exams were scheduled on Friday, June 18, 2021 “to allow for the weekday observance of the Juneteenth holiday.” Friday, June 18 is still an allowable session day, so it is up to the discretion of the district to close in observance or not.
