Current Time in Tell City

Daylight saving time in Tell City

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/Indiana/Tell_City 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/Indiana/Tell_City"))

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

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

How this zone's rules have changed since 1970

Tell City has changed its arrangement 2 times since 1970. This is why a stored offset is not a substitute for the zone identifier — a timestamp from before a change converts incorrectly if you apply today's rule to it.

Boundaries are the years the change took effect, derived from the same IANA database your language's date library reads.

When it is 12:00 in Tell City

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

Zones currently on UTC-05:00

22 other IANA zones are on UTC-05:00 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.
