## Default answer

Example with the default inputs (Time 12:00, In Metropolitan France: Paris, Date September 30, 2026) on the example date Wednesday, September 30, 2026: At 12:00 PM on September 30, 2026 in Metropolitan France: Paris, France has 12 time zones and 13 UTC offsets in use.

## Inputs

| at | Time | A clock time in the zone chosen below; the table shows that moment in every zone. |

## Method

For the typed time in the chosen zone, find the instant (UTC) it names, then show each listed zone’s clock at that instant with its UTC offset, from the browser’s IANA time zone data.

## Assumptions

- The zones are IANA tzdata names from zone1970.tab (tzdata 2026a): Pacific/Tahiti, Pacific/Marquesas, Pacific/Gambier, America/Puerto_Rico, America/Martinique, America/Cayenne, America/Miquelon, Europe/Paris, Africa/Nairobi, Asia/Dubai, Indian/Maldives, Pacific/Port_Moresby, Pacific/Noumea, Pacific/Tarawa. The browser supplies each zone's offsets and daylight saving rules, so a rule change arrives with a browser update.
- “Time zones” counts the different standard offsets among the listed zones. A zone’s standard offset in a year is the lower of its offsets at 00:00 UTC on January 1 and July 1 of that UTC year.
- “UTC offsets in use” counts the different offsets the listed zones show at that moment.
- Each zone shows its local time, the abbreviation from the browser’s Unicode CLDR English names (left out when CLDR has none), the date as “Tue, Sep 29”, the offset as UTC+hh:mm or UTC−hh:mm, and “daylight saving” when the offset is ahead of the standard offset, “standard time” when the zone’s January 1 and July 1 offsets differ but it is on the standard offset, or “no daylight saving” when they are the same. Because the rule compares January 1 and July 1, a zone that moves its offset for good during a year (Cancún in 2015, Novosibirsk in 2016), or whose January 1 falls in Morocco’s Ramadan change (Casablanca in 2030 to 2033), shows the later offset as “daylight saving” for that year.
- A time that does not exist in the chosen zone (skipped when clocks spring forward) has no answer. A time that occurs twice (when clocks fall back) shows both moments, earlier first, where they differ.
- Dates from 2000 to 2040 work.

## FAQ

### How many time zones does France have?

12 across its overseas territories, from UTC−10:00 in Tahiti to UTC+12:00 in Wallis and Futuna, more than any other country. Counts of 13 add Clipperton Island (UTC−08:00), which is uninhabited and has no IANA zone.

### Which parts of France change their clocks?

Only metropolitan France (Central European Time, UTC+01:00, and UTC+02:00 in summer) and Saint-Pierre-et-Miquelon. The other overseas territories keep one offset all year.

### What time zone is Paris in?

Central European Time (CET, UTC+01:00), and Central European Summer Time (CEST, UTC+02:00) from the last Sunday in March to the last Sunday in October.
