Yes, there is a history of Jewish communities in Arab countries relying on the Muslim call to prayer for their own praying times. For one such example, here is the Ben Ish Hai, (Hacham Yosef Haim) who lived from 1832-1909 in Baghdad, and who refers to the maghrab (an Islamic prayer-time called after sunset) in various places: Ben Ish Hai, Year 1, ...

I'm sure that there are modules already written for this purpose (since, after all, there are lots of existing sites and applications that show the parshah of the week, and I doubt each of them reinvented the wheel). I don't know of any that are freely available, though. One way of doing this would be to use lookup tables for each of the 14 possible year ...

He is saying that the year 3724 coincides with the end of a 532-year calendrical cycle. This cycle is when the 19-year machzor katan and the 28-year machzor gadol return to their initial positions (19 x 28 = 532). The year 3724 comes after exactly 7 of those cycles (532 x 7 = 3724). He does not explain why this has any significance.

I had to implement this in Javascript and was successful. So here's the simple programming logic I used: Create an array (or list) of Parshas. Obviously you want to either use transliteration or such. Then used a complex set of if statements to offset based on type of year. To figure the type of year use something like this: function ytype(year){ var a,...

This affects when Shabbat and yom tov start and end and when you can perform time-bound mitzvot. There are various opinions (some collected here), so this is something you need to consult your rabbi on. Opinions cited there include: use the times for your home city (if you're visiting); use 6PM; use the point when the sun is at its lowest in the sky. I ...

I've asked a friend of mine to do me a favor and to write a code for this. Here is what he have done, and here is an example of (my) usage of his code.

See this English translation of a Sicha from the Lubavitcher Rebbe (Likutei Sichot Volume 15, pg 7-12). A short synopsis from here: Now, you, I and the Jewish sages of old all have known for a very long time that eclipses are natural events that can be predicted thousands of years in advance. Thus we can be quite certain that their statement does not ...

Rabbi Dovid Bendory discusses this in a post at this link. For example, he writes, Capital gain on the sale of private property is included as maaser income, but adjust for inflation when computing the cost. Thus, for example, gains on the sale of a personal residence is maaser income. To adjust the cost basis for inflation, use a cost-of-living ...

The sources that I have seen would consider the inheritance as income. For example, someone gives a gift from money that had paid ma'aser on it. This is still considered complete income, because you have not paid any money for it. However, see below that you do not need to pay the ma'aser until you actually liquidate (sell) the property and obtain cash for ...

I am glad you asked this question, esp. just before Rosh Hashanna! I have been wondering about the same thing. You may want to read this article. It states: In the present era the median length of the lunar cycle is about 29 days 12 hours and 30 minutes, the MSM is slightly more than 29 days 12 hours and 44 minutes, the shortest lunations are about ...

I don't have sources, but just based on what I've seen and heard considering practical behavior FWIW. The point of difference is not really taxes versus other expenses. The difference is whether you should give Maaser on Gross income or just on take home pay. A reasonable argument can be made that theoretical money that you don't ever see, and don't have ...

Based on my other answer, Dayan Raskin said that one is allowed to deduct taxes from Maaser, as one never really earns it. It would be similar to one who buys a product for \$100 and sell it for \$150. He really earned \$50. Moreover, he said that in England the tax codes allow one to request that part of his taxes go to charity. For example, if one earned \$...
