Paris time explained
Paris keeps Central European Time, an hour ahead of London, and shifts to Central European Summer Time on the last Sunday in March. The European Union parliament voted in 2019 to abolish the twice-yearly change, but the decision was never implemented, so the clocks still move.
Paris does observe daylight saving, so its offset from UTC changes twice a year. The time above already accounts for whichever is currently in force.
Reaching Paris
The Paris working day covers all of Europe and most of Africa, and reaches the US east coast from mid-afternoon. A Paris morning is the practical window for calling India and the Gulf.
How this page works
The time above is calculated on your own device from the IANA time zone
database that ships with your browser, using the zone
Europe/Paris. Nothing is fetched from a server, and the offset
shown is whatever is currently in force rather than a
number typed into the page — so when a country changes its rules, this
page changes with it.
The difference from your own clock is worked out the same way, comparing Paris's current offset against your device's. If your computer's clock is wrong, so is that comparison.
