Civil twilight is the period when the sun is within 6 degrees below the horizon — bright enough to see outdoors without lights, and what people usually mean by “it gets light” and “it gets dark”. Nautical uses 12 degrees and astronomical 18 degrees. At high latitudes a band can be absent for a whole day, in which case the row is left blank.

Computed from the coordinates of Bettembourg: 49.51861, 6.10278.
Sunrise and sunset are the moments when the centre of the sun is 50 arcminutes below the horizon, which accounts for atmospheric refraction and the sun’s apparent radius — the same convention as common astronomical almanacs. Daylight is sunset minus sunrise; night is taken as 24 hours minus daylight. Elevation, terrain and local weather are not included, so observed times can differ by a minute or two.

How to use this page
The top of the page shows the current date and time in Bettembourg, ticking in the Europe/Luxembourg zone. To convert a specific moment to another city, use the comparison link below, where you can enter a date and time.
How the time is calculated
Bettembourg is bound to the IANA identifier Europe/Luxembourg. The server resolves the UTC offset and daylight saving state for the requested moment and renders the first view; the browser then keeps time in the same zone and re-syncs when the tab comes back to the foreground. No fixed offset stands in for the zone, and no zone is guessed from the city name.
FAQ
- Which time zone is Bettembourg in?
- Bettembourg uses the IANA identifier Europe/Luxembourg, currently UTC+02:00. The same identifier can have different offsets on different dates; the value above is for the current moment.
- Does Bettembourg observe daylight saving time?
- The daylight saving section above answers this from the IANA database: cities that do not observe it show no changeover text, and cities that do show the current state and the next local changeover time.
- What time are sunrise and sunset in Bettembourg today?
- The sunrise and sunset section above gives today’s sunrise, sunset and solar noon along with the length of daylight and night, plus how they change over the next four days. Times are computed from the coordinates of Bettembourg in the Europe/Luxembourg zone; at high latitudes sunrise or sunset can fall on the adjacent date, which the page marks explicitly.
- How many hours is Bettembourg from London?
- Calculated for the current moment: Bettembourg is 1 hours ahead of London. The section above also shows each side’s local date at that same instant. Because the two places start and end daylight saving on different dates, the gap changes during the year — use the fixed-date mode in the comparison tool for another date.
- Can a cached page show the wrong time?
- No. The first render uses server time as a starting value, and as soon as the page loads the browser recomputes the current moment for Europe/Luxembourg and takes over the clock, so a cache hit still shows the time at which you opened it.
