Mayor Bill de Blasio on Thursday finally unveiled his plan for reopening New York City, but it was nothing more than a vague rehash of the state’s guidelines issued weeks ago — and with no firm dates.

“You can expect it to be in the first and second week of June, if the numbers continue to hold or progress,” de Blasio said at his daily press briefing about the city’s comeback — seemingly unaware that Monday is June 1.

He also said, “We do not have a specific date.”

“We’re not going to tell people the day in advance,” de Blasio said. “The day it happens is the day the numbers tell us we’re there.”

Instead of providing specifics, de Blasio reiterated guidelines issued by New York state for phase one businesses, including staying six feet apart and operating under 50 percent of maximum capacity.

New York City is the last of the state’s 10 economic regions to reopen amid the coronavirus pandemic, with neighboring Long Island starting back up on Wednesday.

As of Thursday, 59 people are currently hospitalized in the city for coronavirus, while 6 percent have tested positive for the disease.

“We have never been that low,” de Blasio said of the testing rate. “To date, as we do more and more testing, basically the numbers are going to go down. That’s a great sign for the future of this city.”

Under phase one of New York state’s four-phase coronavirus reopening plan, construction, manufacturing and wholesale supply chains, and retail businesses with curbside pickup or in-store pickup only can reopen, as well as businesses in agriculture, forestry and fishing.

The frequently time-challenged De Blasio has repeatedly suggested the city is set to reopen in early June. But with the first of the month around the corner, he has yet to release a concrete plan of action, leaving business owners in the lurch.
