Here are some closings and changes due to Memorial Day weekend for your planning purposes.

Parking meters in Wellesley will be free on Monday.

Wellesley’s RDF will be closed on Monday.

Wellesley town offices will be closed Monday.

Memorial Day is an official holiday for the US Postal Service, so Post Offices will be closed on Monday and there will be no home delivery of mail. It is also an official holiday for UPS, but scheduled UPS Critical Express and UPS Holiday packages should still arrive.

Brace yourself for this one, and plan accordingly: Massachusetts law states that liquor stores must be closed on Memorial Day.

The Wellesley Free Library will be closed from Saturday, May 27th through Monday, May 29th in observance of the holiday.
