Current Time in Puerto Rico

Daylight saving time in Puerto Rico

Puerto Rico does not observe daylight saving time. Its offset stays at UTC-04:00 every day of the year, which makes it one of the simpler zones to work with: a fixed offset is enough to convert any timestamp, and there are no missing or repeated local hours.

Converting timestamps for this zone in code

Always pass the IANA identifier America/Puerto_Rico rather than a numeric offset. The identifier carries the zone's entire history of offset and daylight saving changes, so a timestamp from any year converts correctly; a hard-coded offset is only right until the next rule change.

# Python
from datetime import datetime
from zoneinfo import ZoneInfo
datetime.fromtimestamp(1710050400, ZoneInfo("America/Puerto_Rico"))

// JavaScript
new Intl.DateTimeFormat('en-GB', { timeZone: 'America/Puerto_Rico',
  dateStyle: 'full', timeStyle: 'long' }).format(new Date(1710050400 * 1000));

<?php // PHP
(new DateTimeImmutable("@1710050400"))->setTimezone(new DateTimeZone("America/Puerto_Rico"));

How this zone's rules have changed since 1970

Since the start of Unix time in 1970, Puerto Rico has kept a standard offset of UTC-04:00 and has never observed daylight saving. A zone this stable is forgiving to work with: a timestamp from any year in that span converts with the same rule that applies today.

When it is 12:00 in Puerto Rico

Midday here against the clocks most schedules are written around, for Thursday, 22 October 2026 at 12:00:00 AST:

Zones currently on UTC-04:00

46 other IANA zones are on UTC-04:00 at this moment. They agree on the clock today but not necessarily tomorrow — zones that observe daylight saving on different dates diverge and rejoin through the year, which is why an offset alone can never stand in for a zone.
