MOled -- Why is it always not on the same day as Rosh Chodesh?
Is the calendar off? Or did this have something to do with when the 
witnesses would come?

	The moled is the beginning of the new month, meaning, the time when
 the new moon can first be seen. a lunar month is 29 days, 12 hours, 44
 minutes and one chalek ( 1/18 of a minute ) long. 

	In the time of the Temple, and imediately following it, the new month
 was decreed to start by the court sitting in the Temple ( and after the 
 destruction, by the same court, just not in its old quarters ). The judges
 of the court could not decide on their own when he new onth was to start.
 Rather, witnesses would come, testifying that they had see the new moon. The
 judges would cross-examine the witnesses thoroughly to see if they were lying
 and if the judges were satisfied with the testimony, they could declare the
 new month to begin.

	The court was empowered though, if it saw a need, to delay the sart
 of the new month. Since the whole process was given to the court to decide
 ( as is learned from the verse Exodus, 12, 2 ) This month is to you the
 head of the months... The Torah said it was given to the court to decide 
 when to declare the new month, so they could delay it. They could not, 
 however, declare the month to start early ( before witnesses came ). Also
 they could only delay it one day, since a month has either 29 or 30 days
 in it.

	In the times of the witnesses, the moled could have been the day of
 Rosh Chodesh ( new month ) if te witnesses came quickly. Otherwise it would
 be te next day, the day they came to testify in court.

	When our present calendar was set up it was arranged in such a way
 that certain occurrences would not happen. Yom Kippur was always arranged
 to not fall out on Friday or Sunday ( because there would be two successive
 days when food could not be prepared ). Therefore, the first day of Pesach
 cannot come out on either Monday or Wednesday. It cannot fall on Friday
 either, because then Hoshana Rabba, when we take the willow in shul, would
 fall on Shabbat, and we wouldn't be able to go around. Hoshana Rabba, is the
 day before Shmini Atzeret, and both are considered days when we are judges as
 to how much rain will fall in the coming year.

	Because of these considerations, the new month does not always 
 coincide with the moled. 

	Another point. The time announced as the moled is in Jerusalem local
 time, since the new month's declaration was always in Jerusalem. Therefore
 it is possible to come to shul and say ( at 10:00 am ) the moled was this
 afternoon at 2pm ( since 10 am in America is after 2 pm in Jerusalem ).

	This whole discussion appears in many places in the Talmud, including,
 as I recall, Tractate Rosh Hashana.

Why is the Molad not always the same day as Rosh Khodesh?
Because of several sources of discrepancy:

1.  The molad is calculated by a fixed formula, which is erroneous by about
one second every month.  It is currently about 4 hours off from the true
instant of new moon.  This accuracy is perfect within the grain of the
calculation, which has 3-1/3 seconds as the smallest unit.

2.  The time of the molad is given in Jerusalem Standard (not mean) time.  

3.  The day of Rosh Khodesh is calculated by a fixed formula that gives each
month a set number of days.  (The second and third months have either 29 or 30
days depending on the total number of days in the year, but the formula is
fixed.)  Rosh HaShono is usually pretty close to the first Molad (although it
can be delayed by 2 days for various reasons, such as to prevent Yom Kippur
from falling on Friday).  Near the middle of the year, the discrepancy between
Molad and Rosh Khodesh can be fairly large (a day or so).

4.  Months that have 30 days cause the Rosh Khodesh of the next month to be
celebrated for two days, on the 30th of the previous month and the 1st of the
next one.  So one shouldn't expect the Molad to fall near the first of those
two.

By the way, almost every published calendar I have seen gave the wrong time for
the Molad a few months ago.  I wonder why we so carefully announce the Molad in
shul, since it seems fairly unimportant.

I believe there is a much more important reason:  If Yom Kippur were to
fall on Friday or Sunday, there could be too long a period during which
the dead could not be buried.

	There is an opinion, as I remember vaguely, that announcing the molad
 is in commemoration of the Sanhedrin's ( court in the Temple ) announcing the
 new month. Without the formal announcement, the month would not start. So we
 commemorate it by announcing the molad. ( I would imagine that at least one
 shul [ in Jerusalem ] would be required to announce the month in order for
 it to be considered Rosh Chodesh ). I do not remember where is saw this 
 opinion so I cannot quote a source, I just remember reading it somewhere.

Eliyahu, isn't the reason because we do not want to have to leave a 'meis'
(dead body) for two days (Shabbos & Yom Kippur) without burial ? Especially
in the times of the Gemarrah when there was no refrigeration.

I seem to recall that the problem with Yom Kippur coming out on Friday
or Sunday was that there would be two successive days when a body
could not be buried.  Can anyone back me up on this ?
Besides what the problem with not being able to prepare food ?  So you
don't have hot food on one of the days.  As a side point, who eats
on Yom Kippur ??????

I still agree with the original poster "Why is the Moled so different" ?
Does anyone have a calendar with Moleds ?  I can't recall even ONE
Moled that is close to Rosh Chodesh (EVEN Israel time).  I would think
that on average we'd see most Moleds be within a day of the Chodesh,
that's not the way I remember it each month.  Can anyone concur with
me on that ?

	True. My mistake.
