PAT
Punta Arenas Time
Punta Arenas Time (PAT) covers Chile’s Magallanes region, including the city of Punta Arenas, and stays on a steady UTC‑03:00 year‑round. Because this region sits so far south on the globe, you’ll notice dramatic swings in daylight—midsummer sunsets after 10 p.m. and dark winter afternoons—yet the clocks never change, keeping scheduling simple when working with teams outside Chile’s mainland or across the Strait of Magellan.

IANA zones · the technical identifiers
The zone that resolve to PAT.
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 PAT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Is Punta Arenas Time the same as the rest of Chile?
- No. Most of Chile, including Santiago, uses UTC‑04:00 in winter and UTC‑03:00 in summer, while Punta Arenas Time is fixed at UTC‑03:00 year‑round: one hour ahead of Santiago in winter and aligned with it in summer.
- Why does PAT never change its clocks?
- In December 2016 the Magallanes region stopped changing its clocks and kept summer time (UTC‑03:00) all year, giving residents more daylight in the evening.
- What’s unique about daylight in Punta Arenas?
- Around the December solstice the sun sets after 10 p.m., while around the June solstice it rises at about 10 a.m. and sets around 5:30 p.m., giving residents huge seasonal differences in lifestyle and work patterns.
- How does PAT affect communication with global partners?
- Because it’s always UTC‑03:00, Punta Arenas is 1–2 hours ahead of New York (depending on U.S. daylight saving) and 3–4 hours behind London, so it overlaps well with the Americas and with Europe's afternoon.
- Which cities use PAT?
- Primarily Punta Arenas and surrounding areas in Chile’s Magallanes region, including parts of the Strait of Magellan and Chilean Antarctica claims.
- Is PAT the southernmost time zone used in daily life?
- It’s one of the southernmost stable time zones. Further south, research stations often self‑select offsets, but PAT is the last truly official, populated time zone before you reach Antarctica’s flexible clocks.
- How does PAT relate to nearby Argentine time zones?
- Argentina, including Buenos Aires and Ushuaia, uses UTC‑03:00 all year without daylight saving, so Punta Arenas and Argentina always show the same time.
