The complete 2023 Shabbat calendar for Houston: candle-lighting and Havdalah times for all 52 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 Houston's exact coordinates (29.7604°N, -95.3698°E, elevation 15m) 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 2023 in Houston, calculated from precise NOAA solar algorithms for the city's exact coordinates and elevation, 18 minutes before sunset.
What time is Havdalah in Houston in 2023?
Havdalah times for every Saturday night of 2023 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 Houston, 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 52 weeks of 2023 are computed the same way, using the same algorithm as our weekly Houston page. Daylight saving time is already reflected in the times shown.
