Market Basket is adjusting the closing time at all store locations starting Monday, related to the outbreak of the coronavirus.

The grocery chain’s CEO, Arthur T. Demoulas, announced Saturday all locations will close three hours earlier, shutting doors to shoppers at 6 p.m. daily. Shopping hours just for seniors will continue Tuesday, Wednesday, and Thursday between 5:30 a.m. and 7 a.m. The markets will open at 7 a.m. daily to the general public.

Beginning Monday March 23, 2020, all Market Basket stores will be open every day from 7:00 AM – 6:00 PM.

Demoulas said the change will allow store workers to better prepare for the next day of business.

“We are committed to serve our customers and community in the best possible way during this challenging time,” he said. “The adjusted closing hour of 6 p.m. is to provide our hard working associates the opportunity to rest and recharge, while we utilize the evening hours to stock and prepare our stores for the next day’s business. The heart and soul and stamina of the Market Basket team along with the tremendous support and understanding of our customers is remarkable and greatly appreciated.”
