Can I schedule a meeting for 7:30pm on 10/5/05?  That is the last day of Rosh Hashanah, sundown is 6:46pm.  Would 7:30 be okay?   Does it just go by sundown? Or is there a specific time?

I need to get this done and I have no idea who to ask.

I did call a local synagogue, and got an answer of "I'm not sure" if you can believe it.
