Function: tzAbbrev()

tzAbbrev(instant, timeZone): string

Defined in: src/lib/dates/tz.ts:62

Short timezone label (e.g. "EST"/"EDT") for instant in timeZone, for display.

The abbreviation is DST-aware: the same timeZone yields EST vs EDT depending on whether instant falls in standard or daylight time. Display-only — not a parseable offset.

Parameters​

instant​

Date

The absolute point in time (a UTC-based Date) whose DST state selects the label.

timeZone​

string

IANA timezone identifier (e.g. America/New_York).

Returns​

string

The short timezone name from Intl (e.g. EST, EDT). Falls back to the raw timeZone string if the runtime cannot produce a short name.

Throws​

RangeError If timeZone is not a valid IANA identifier, or if instant is an invalid Date.
