Daniel Matson wrote and asked:  "Any thoughts on the time of day we will hear
the trumpet?"

Rosh Hashanah is to be on the first day of the seventh month, Tishri 1.  The
first evening a waxing crescent moon is visible marks the start of the Jewish
month, Rosh Chodesh.

On Friday, September 22, for an observer in Jerusalem, the sun sets at 6:36pm
local daylight savings time.  The moon sets just two minutes BEFORE the sun
this evening at 6:34pm local daylight savings time.  This is the evening of a
true new moon, one that gives no light.

So the first waxing crescent of the new moon would not be visible to two
reliable witnesses until the following evening.  This is the case ... on
Saturday, September 23, the sun will set at 6:35pm local daylight savings
time.  The moon sets at 6:58pm local daylight savings time.

My understanding is that the shofar was blown upon receipt of a report from
two reliable witnesses that the first waxing crescent of the new moon was
visible.

So, the new moon would become visible on the evening of Saturday, September
23, some time after 6:35pm local (Jerusalem) daylight savings time and before
the moon setting at 6:58pm local (Jerusalem) daylight savings time.

These times correspond to between 8:35am and 8:58am Pacific Daylight Savings
time on the morning of Saturday, September 23.

(The new moon, one that gives no light, actually is the evening of September
22.  Perhaps this explains why Rosh Hashanah is on Friday evening-Saturday
this year.  However, without the aid of computer modeling software for the
skies, this would not be knowable.  My understanding, as noted above, is that
the start of the Jewish month didn't happen until the first waxing crescent
of the new moon was actually VISIBLE.  This would seem to put Rosh Hashanah a
day later than actually is the case.  Perhaps someone could help clarify
this, as I am at a loss.)

In Christ,
