What Hour Can’t We Make Kiddush? There’s A Website For That
by CrownHeights.info
It’s a question that comes up each year when we turn our clocks back and shabbos is early. What time can’t we make kiddush?
The custom of not making kiddush during the 7th hour is mentioned in the Alter Rebbe’s Shulchan Aruch 271:3, and is widely confused as an exact hour as on a clock.
The start and end time of the 7th hour is designated by each location’s longitude, which usually will not coincide with the even hours on the clock.
To help people easily find the hour in their area, https://7thhour.info/ was created that easily and simply identifies the hour based on an address, city, or Zip Code. The english language site has a hebrew version, which can be found at https://7thhour.info/?lan=1.
The formula that is used on this website was approved by Dayan Rabbi Levy Y Raskin in London, UK.
