The astronomical method uses the time that it takes to see three small stars in Israel and position of the sun relative to the horizon at that time to extrapolate when Shabbat should end for the rest of the world. In Jerusalem, during the Tishrei and Nissan equinoxes, it takes approximately 36 minutes after sunset to see these three stars in the sky. At this time, the sun is 8.5 degrees below the horizon. Therefore, Shabbat ends when the sun is 8.5 degrees below the horizon, post-sunset, in every other location in the world. <ref>Rabbi Yechiel Michel Tukachinsky, Sefer Bein HaShemashot.

In light of this calculation, the amount of time after which Shabbat will end will vary from place to place in the world. | |||
