ZoneIdofAmericaNewYork

ZoneId America/New_York is the IANA time zone identifier that represents the Eastern Time Zone of the United States, including the state of New York. It is the canonical ID in the IANA Time Zone Database (tz database) used by many software systems to model local times and time zone rules for the region.

The zone observes Eastern Standard Time (EST, UTC-5) during the non-daylight-saving period and Eastern Daylight Time (EDT, UTC-4) during daylight saving time. Daylight saving time in this zone begins on the second Sunday in March and ends on the first Sunday in November, with transitions typically occurring at 2:00 a.m. local time.

In software development, America/New_York is used to compute and convert timestamps, schedule events, and store date-time values in a time-zone aware manner. The tz database is maintained by IANA and provides the rule sets for this and other zones, allowing applications across languages and platforms to align with local time changes and historical data.

The geographic scope of the America/New_York identifier reflects the Eastern Time practices in the United States, including the state of New York and other regions that share the same time rules. As time zones can be affected by legislation and policy changes, the tz database updates periodically to reflect any alterations in standard time or daylight saving transitions.
