Halachic Times for Jerusalem ZMANIM - HALACHIC TIMES - Correct for TT #637 All other places at some height above sea level have similar problems. Tzfat lights candles 30 minutes before sunset. Official candle lighting for Petach Tikva is 40 minutes before sunset, just like Jerusalem. Not everybody holds by that timing. Some communities calculate Shabbat out at 33 minutes after sunset. Some use the angle of the sun below the horizon to “end Shabbat” (8.5 deg). Bottom line for now: until we get the chart running smoothly, don’t rely on it exclusively. Cross-check times with calendars and charts. Please report discrepancies to us, so that we can improve our time table. Also realize that Sfardim and Ashkenazim often has
differences in minhag. Sunset, on the other hand, is given for an elevation of 825m and, in parentheses, as if at sea level. There are different opinions as to which sunset time should be used for halachic purposes. We present both times. The deadlines for the SH'MA and the Shacharit Amida can be calculated in two ways. Either considering the day to be from sunrise to sunset or from dawn to stars out. The first way of reckoning is known as the opinion of the GR"A, and is the first time given in each case. The second method is known as the Magen Avraham, and is presented in parentheses. Aside from candle lighting and havdala, the times are presented as a range, from the current Thursday of the issue of Torah Tidbits until the coming Thursday, a span of 8 days. Days between the two Thursdays can be determined by interpolation (which means: a method by which to estimate a value of between two known values-this is something that people above a certain age might remember from high school trigonometry and logarithms, but younger people who went to school during the calculator era might not be familiar with). It is usually wise to "pad" the times with a minute or two in the "play it safe" direction. E.g. Plag Mincha. Better to finish Mincha a minute or two before the given time. But, better to not light candles until a minute or two after the given time. [The Sukkot Homepage]
