[Avodah] Molad Alert: Friday night

[kennethgmiller at juno.com]

Many thanks to R' Zev Sero for an excellently detailed post.

I had written:

and he corrected me:
> Huh?  Surely it's nearly 21 minutes. 19 minutes, at J'm's

Thanks for the correction. To tell the truth, I carefully did my calculations while I was writing that post, and when I got to the end, I had calculated that midday in Yerushalayim occurs at 12:20 Time Zone Time. I looked at that and said, I *know* that's wrong, I *know* that it is *before* 12:00.

I had to reread the calculations several times before I found the error: My current galus in the Western Hemisphere, and my frequent calculations to the nearby 75° West line, had caused me to get many of the additions and subtractions reversed. So too again with this last one-minute adjustment.

Thanks again
Akiva Miller
