Constantine does not change its clocks
A fixed offset, all year round
Constantine stays on Central European Standard Time at UTC+01:00 every day of the year. There is no spring-forward or fall-back here, which puts it with the majority: most of the world's time zones do not observe daylight saving.
That sounds like it makes scheduling simpler, and locally it does — but it introduces a different trap for anyone working with Constantine from a country that does change clocks. The offset between you and Constantine is not constant: it changes when your clocks move, even though nothing changed here. A recurring call that has run at the same local time for months will shift by an hour, from your side, without anyone editing the invite.
When the gap to Constantine changes
Dates in the next year where the difference shifts, by counterpart city
The difference between two cities is not a constant. It changes whenever either side moves its clocks — and because regions switch on different dates, there are short windows each year when the usual gap is wrong. These are the dates that matter for Constantine:
London (United Kingdom)
- From 25 October 2026: Constantine is 1 hour ahead of London
- From 28 March 2027: Constantine is on the same clock
Paris (France)
- From 25 October 2026: Constantine is on the same clock
- From 28 March 2027: Constantine is 1 hour behind Paris
Dubai (United Arab Emirates)
Neither Constantine nor Dubai changes its clocks in the next year, so the gap between them stays fixed. One less thing to track.
