Alas that the world is using Hillel's calculations for a Diaspora Calendar, and the New Moon is not yet risen, even in Israel. it is currently at 0.9%, and is below the horizon.
Alas that they are still using Hillel's Calendar for the Diaspora...observation will not place Rosh haShanah until tomorrow (9/22/17). Yet still, may we all have a blessed and sweet year!
