It’s the dawn of a new “Day.”

Greg Kelly is leaving “Good Day New York,” Page Six has learned.

Sources tell us former ABC morning anchor Lori Stokes will join the Fox 5 morning show as co-host with Rosanna Scotto.

Lew Leone, FOX-5 WNYW vice president and general manager, exclusively told us: “We want to thank Greg for his years of service. He has been an integral part of the FOX 5 team and we wish him the best of luck in the future.”

Kelly’s last day is Friday and we hear the show will air a goodbye package as a sendoff.

He joined the show in 2008.

Sources say Stokes will step into Kelly’s role “in a few weeks” and Steve Lacy will fill in next week.

As for his next move, the outgoing anchor was coy.

“There are some other things I’m excited about doing and I am very, very grateful for all the time I’ve had here and for all the people who make this show possible,” he said on the show Friday morning.
