Updated:Target has expanded its shopping hour for vulnerable guests to twice a week.

All Target stores will close no later than 9 p.m. local time starting March 18, the retailer announced.

The Minneapolis-based retailer is one of the last major companies to cut hours in response to the coronavirus or COVID-19 to give staff "additional time for cleaning and restocking each day," the company said in a news release. Walmart reduced hours of its 24-hour stores on Sunday as have many grocery stores.

Target stores that regularly close earlier than 9 p.m. will continue to close at their normal time, the company said. Updated store hours are posted at Target.com and in stores.
