The complete 2100 Shabbat calendar for Seattle: candle-lighting and Havdalah times for all 53 weeks of the year, with the weekly Torah portion and holiday Shabbatot flagged. Candle lighting is listed 18 minutes before sunset; Havdalah follows Tzais HaKochavim (72 minutes / 8.5°).
Every time above is computed from NOAA solar position algorithms for Seattle's exact coordinates (47.6062°N, -122.3321°E, elevation 53m) and its time zone, including daylight saving changes automatically. Candle lighting follows the local community custom of 18 minutes before sunset.
The table above lists the Shabbat candle-lighting time for every Friday of 2100 in Seattle, calculated from precise NOAA solar algorithms for the city's exact coordinates and elevation, 18 minutes before sunset.
What time is Havdalah in Seattle in 2100?
Havdalah times for every Saturday night of 2100 are listed in the table above, calculated at 72 minutes after sunset (Tzais 8.5 degrees). Many communities follow Rabbeinu Tam — about 50 minutes later.
Why do Shabbat times change every week?
Sunset shifts throughout the year as the Earth tilts on its axis, and the shift is larger the farther a city is from the equator. In Seattle, candle lighting and Havdalah can move by an hour or more between the shortest and longest weeks of the year.
Are these times accurate for the entire year?
Yes. All 53 weeks of 2100 are computed the same way, using the same algorithm as our weekly Seattle page. Daylight saving time is already reflected in the times shown.
