How the Grand Duchy keeps its time
- From a meridian to UTC (LUX)
- +1 h
- Before its amendment, the first article of the time law tied legal time to the fifteenth meridian east of Greenwich. It named that meridian's mean time, Universal Time plus one hour. The amending law now defines legal time as Coordinated Universal Time plus one hour. The new text names that base value UTC (LUX). The parliamentary file says the value of legal time did not change.
- Two atomic clocks at ILNAS
- 2
- The law gives the Bureau luxembourgeois de métrologie, part of ILNAS, the task of determining and disseminating UTC (LUX). An ILNAS laboratory generates legal time with two high-performance atomic clocks. Redundant equipment keeps its synchronisation signals going through an equipment fault or a power cut. The bureau also supplies the BIPM with the UTC value for Luxembourg.
- Summer time by regulation
- Art. 2
- The time law lets a grand-ducal regulation modify legal time as its first article defines it. A draft regulation on summer time sits in one of the Conseil d'État's files. The draft cites the EU summer-time directive, which sets that system for an indefinite period. No adopted version of the draft was found when this page was checked.
- Unified time and an October decree
- 60 min
- Time across the Grand Duchy was the subject of a unification law early in the twentieth century. A grand-ducal decree issued shortly before the Second World War cites that law. It put the clocks back sixty minutes at one in the morning, on a night at the start of October.
Questions about time in Luxembourg
What time zone is Luxembourg in?
Luxembourg is on Central European Time, CET, UTC+1, outside summer time. For summer its clocks go one hour ahead to CEST, UTC+2. The zone table of the time zone database holds one entry for Luxembourg, so no region runs differently.
When do the clocks change in Luxembourg?
Luxembourg's clocks spring forward one hour at two in the morning on the last Sunday in March. They fall back one hour at three in the morning on October's last Sunday. Those two Sundays come from the EU summer-time directive. The draft national regulation names the same two hours.
Will Luxembourg stop changing its clocks?
No end has been decided. The European Commission proposed stopping seasonal clock changes, with each member state picking its own standard time. The European Parliament's position supports ending the changes. The Council is yet to give its first-reading position, so the proposal has not become law.
What is the time difference between Luxembourg and the UK?
London is 1 hour behind Luxembourg all through the year. Clocks in both countries go forward together in March and back together in October. A call at eight in the morning in Luxembourg is at seven in London.
What is the time difference between Luxembourg and New York or Los Angeles?
New York is 6 hours behind Luxembourg for most of the year. Los Angeles is 9 hours behind Luxembourg. Both cities start summer time two or three weeks before Luxembourg does. In autumn they end it one week after. During those weeks, each difference is an hour less.
