Is the New York temple Closed? Also what time is sacrament meeting on Sunday?

Yes currently the temple is closed until Monday October 28th. They are doing some maintenance. But at the same building you can find a sacrament meeting on Sunday at 10:30 and another one at 12. Also on 87th Street they have a sacrament meeting at 9:30

I'm sure if you call the temple they can tell you all the information that you need.

I can't remember the time for Sacrament meeting, but if you call the Temple, they will tell you.
