You sure you want to open up this can of worms? :-) Here's the situation. There is no explicit mention of any such concept in the Torah, Talmud, or adressed by the Rambam, the Rosh, the Tur, or the Shulchan Aruch. The first time this really became an issue when during WWII when yeshiva students (notably those from Mir and Chachmei Lublin) relocated from ...

The Talmud (Pesachim 54b) states that only for Tisha bAv must we be stringent for Bein Hashemashot. There is an opinion in Rishonim that only regarding the Bein Hashemashot at the beginning of the day is Tisha bAv unique, but all fasts require being stringent at the end because we have to wait until it is certainly night to uproot the current status (chazaka)...

Shulchan Aruch O.C. 672:2 שכח או הדד ולא הדליק [....] ומיהו הני מילי לכתחילה; אבל אם עבר זה הזמן ולא הדליק, מדליק והולך כל הלילה. ואם עבר כל הלילה ולא הדליק, אין לו תשלומין If one forgot and didn't light, or purposefully didn't light [....] however, this is only lechatchila; if [the end of sunset] has passed and one didn't light, they should light for the ...

Shulchan Aruch Orach Chaim 47:13 rules that one who wakes up early to learn should make birchot hatorah before he starts learning, even if that is before the start of daylight. One does not repeat the blessings after it becomes light.

Only Yom Kippur and Tisha b'Av are 25-hour fasts. The others are minor fasts, from dawn (first light, before sunrise) until nightfall (full dark). The minor fasts are: Fast of Gedaliah (3 Tishrei) 10 Tevet Fast of Esther (13 Adar) Fast of the Firstborn (for those to whom it applies) (14 Nisan) 17 Tamuz You can read more about these fasts at Judaism 101.

YU Torah online has a good summary. The subject is disputed by the Vilna Gaon and Rabbeinu Tam. The first allows only up till sunset; the second up to when the stars appear. Mishna Berurah 233:14, limits the leniency to recite Mincha until tzeit hakochavim. He cites the opinion of P'ri Megadim, Eshel Avraham 233:7, who rules that one cannot ...

Ultimate Zmanim for iOS has that feature. With Zmanim Alarms, Ultimate Zmanim can remind you of important zmanim throughout the day. Shema, Tefila, and weekly candle lighting are all covered. (To forewarn the question, on Android, Halachic Times is an equivalent).

The proprietors of goDaven were kind enough to supply me, for the purposes of answering this question, with their table of 5,960 mincha and/or maariv services. I used a Perl script to extract 1,046 where weekday mincha both preceded maariv and was listed as a certain number of minutes before sunset, p'lag, tzes, or candle-lighting time. Because some times ...

It is well know that there is a disagreement whether one should light Channuka candles at sunset or at tzet hakochavim. However, the basis for this disagreement is less known, and this I will try to clarify. The Gemara (Shabbat 21b) states that one should light candles "mishtishka hachama". This expression appears in other places in shas as well including in ...

As long as we stay well (Stockholm is 7°/800 km/500 mi) south* of the polar circle, there will always be a sh'kia and a netz . Therefore, all zmanim can be calculated. Even a tzeis and an alos can be calculated by relying on the opinion that they occur a fixed number of minutes* (e.g. 72) after shkia and before tzeis. Let's take some practical examples: On ...

According to Rabbi Shlomo Fisher on ohr.edu, someone flying is exempt from lighting, because the rule is one candle per household ("נר איש וביתו;" Shabbos 21b); and if there's no one at home then there is no obligation to light.

The Be'er Hetev that you quote says that if Saturday night is before the third of the month, Kiddush Levana should be pushed off to the next Saturday night because it will still be before the 11th of the month (and we don't usually push off Kiddush Levana to Saturday night if it will be after the 11th of the month for fear of a few days of clouds). But he ...

No it cannot. In fact, one cannot even recite shema twice in the period between alot hashachar and hanetz hachamah to count for the evening and morning readings. Shulchan Aruch Orach Chaim 58:5: אם נאנס ולא קרא ק"ש ערבית עד שעלה עמוד השחר כיון שעדיין לא הנץ החמה קורא ק"ש ויוצא בה ידי חובת קריאת שמע ערבית ואם היה אנוס באותה שעה לצאת לדרך מקום גדודי חיה ...

He should say Shema absolutely immediately as the printed time may not be completely exact. (See ShA OC 46:9 with commentaries. The assumption there is that one who can't say the blessings of Shema then (because he needs to say them just prior to his Amida which must be said with a Minyan) should still say Shema at its proper time without its blessings even ...

In Talmud Bavli Rosh Hashanna 20b, R' Zeira quotes R' Nachman as saying: כ"ד שעי מכסי סיהרא לדידן שית מעתיקא ותמני סרי מחדתא לדידהו שית מחדתא ותמני סרי מעתיקא For 24 hours, the [moon] light is covered: For us [in Babylon] - 6 of the old [month] and 18 of the new [month]; for them [in Jerusalem] - 6 of the new and 18 of the old. (Translation mine, ...

Regarding Havdalah during the week, I believe the reason why you find the Rebbe doing is so is because he actually keeps Shabbas until Tuesday. I heard this from a well-known story that the Gedolim weren't sure of this minhag and sent Rabbi Chaim Kanievsky to speak to the Rebbe. Although he didn't know the source for the Rebbe's custom, after the ...

From http://ravbaruch.com/AskTheRabbi.asp?QID=92#_ftn2: Reportedly, Rav S. Z. Auerbach z’’l and Rav Moshe Feinstein z’’l ruled that if one experiences two sunrises on the same day of the week, one is obligated in only one tefilloh. The time cycle for tefilloh is once a day, regardless of how many nightfall’s and sunrises there are on that day. Since they ...

Tractate Brachos of Talmud of Babylon 3b says this is a dispute between 2 tanaim (Rabbis in the period of the Mishna just under 2 millenia ago) whether there are 3 or 4 watches in the night: תנו רבנן ארבע משמרות הוי הלילה דברי רבי רבי נתן אומר שלש The Sages taught in a Tosefta: The night is comprised of four watches; this is the statement of Rabbi ...

From: http://www.torah.org/advanced/weekly-halacha/5757/chaysara.html One should be extremely careful to finish davening Mincha by Shkiah, sunset, since many early Poskim (12) hold that it is forbidden to daven Mincha after that time (13). It is better to daven on time without a Minyan than to daven after the proper time with a Minyan (14). B'dieved, one ...

NOTE: both of these are only partial answers; the 1st may be against the Rashba and the 2nd is disputed First Answer The simplest answer might be that the times of getting up and going to sleep are based on when non-Jews, who are exempt from Shema, wake up (after all, non-Jews do make up the vast majority of the human population). Rishonim (see Tos. 2b) ...

If you really need to, you can say Maariv and Havdalah (omitting the blessing on the candle) from Plag HaMincha (1.25 hours before sunset) (ShA OC 293:3) just as much as you can say Maariv and Kiddush after that time on Friday. The blessing on the candle can be recited separately after nightfall. All labor remains forbidden until after nightfall (even after ...

The argument does indeed apply across the board. Perhaps you see it discussed most about the last time for reciting Shema since that's the only time during the day with potential biblical consequences, leading some to be more stringent.

Interestingly the Pitchei Tshuva on SA YD 89:1, in the context of eating meat after milk, brings an opinion from Beer Heitev shel Maharit that these could be shaot zemaniot. He quickly writes the Pri Megadim, Hokhmat Adam and Knesset Hagedolah disagree and the minhag is not to use shaot zemaniot. עבה"ט של מהרי"ט ז"ל אם הם שעות זמניות. ועיין כו"פ ופמ"ג ...

What is called the time of mincha is actually the time of the afternoon tamid (for explanations of the name, see Tosafot Pesachim 107a). The afternoon tamid was generally slaughtered at eight and a half hours into the day and sacrificed at nine and a half hours into the day (Pesachim 5:1; see there for when it was slaughtered earlier on Erev Pesach). Since ...

For definitive halachic advice, CYLOR as usual. See B'rachos (29a) where Sh'mu'el HaKatan forgot the text of the prayer that he had just instituted (V'lamalshinim), and he stood there for two or three hours until he finally remembered the formulation. If you're not confident in your memorization, and you think it is possible that you might forget some of the ...

Shulchan Oruch Orach Chayyim 30 (2) MB [3, 4] forbids wearing Tefillin at nighttime. MB explains that this is a Rabbinic prohibition in case he would fall asleep wearing them and emit wind from below. The source seems to be the gemoro in Shabbos 49a about half-way down. The link here will show you where to access the gemoro text to paste in. א"ר ינאי ...

Mincha Gedola is three hours long thus it is the big Mincha. Mincha Ketana is 2 1/2 hours long thus it is the small Mincha. Regarding Plag Hamincha it is the time in between Mincha Ketana and Shekiya, which is half of the time of the Mincha remaining. It does not mean the half time between the two Minchas as there is no Halachic significance to that time. ...

You can avoid any concerns about chillul Hashem by intercepting and correcting the negative impression your gentile coworker has of you. The problem here is an education gap, which you can fix. Your coworker believes that Shabbat starts at a particular time and that this is when all Jews start it. He took your "they're starting early" to mean "they're ...

R' Sh'lomo Zalman Auerbach indicated that it would be acceptable to rely upon an alarm for eating if the alarm is functional, although it should not be relied upon to wake oneself from sleep (Halichos Sh'lomo, T'filla 2:12). R' Bentzion Abba Sha'ul also indicated it would be acceptable to rely upon an alarm clock for eating, provided that the person ...

A blog in The Times of Israel makes it clear that the normal time of lighting (“as soon as possible after nightfall”) is observed in Melbourne Australia: For starters, it only gets dark well after 9pm. There’s no rush to get home in time to light at dusk, and dinner is all over by candle lighting time. Indeed, we have to keep the smaller children up ...
