Current Time in Boise

Daylight saving time in Boise

This zone shifts its clocks twice a year, so its offset from UTC depends on the date. In 2026 the transitions fall at:

Around the forward transition an hour of local time does not exist, and around the backward transition an hour occurs twice. Any job scheduled at a wall-clock time inside those windows will be skipped or run twice — the reason recurring work should be scheduled in UTC. See daylight saving bugs.

Converting timestamps for this zone in code

Always pass the IANA identifier America/Boise 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/Boise"))

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

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