PMST
St. Pierre & Miquelon Standard Time
St. Pierre & Miquelon Standard Time (PMST) is used by this small French territory just off the coast of Canada. It observes daylight saving time on the North American schedule, moving one hour ahead to UTC-02:00 from the second Sunday in March to the first Sunday in November, so it changes clocks on the same dates as neighboring Atlantic Canada.

IANA zones · the technical identifiers
The zone that resolve to PMST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about PMST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Is Saint Pierre and Miquelon always on the same time as nearby Newfoundland?
- No — Saint Pierre and Miquelon is always 30 minutes ahead of Newfoundland. Both switch on the North American schedule, in March and November, rather than on the European pattern.
- Why does UTC-02:00 look unusual for a territory near Canada?
- UTC-02:00 is only the daylight saving offset, used from the second Sunday in March to the first Sunday in November. Standard time is UTC-03:00, one hour ahead of Atlantic Time in Nova Scotia and New Brunswick.
- How can I check the current offset?
- The live clock at the top of this page always shows it: UTC-03:00 in winter and UTC-02:00 from the second Sunday in March to the first Sunday in November.
- When do clocks change in Saint Pierre and Miquelon?
- Clocks move forward one hour to UTC-02:00 on the second Sunday in March and back to UTC-03:00 on the first Sunday in November.
- Does Saint Pierre and Miquelon observe European DST rules?
- No — despite being a French overseas collectivity, it follows the North American daylight saving schedule instead of the European spring-forward/fall-back dates.
- Is PMST a common abbreviation?
- Not very. PMST and PMDT appear in some references, but most sources, including the time zone database, simply write the offset as −03 or −02.
