IRST (Irish Standard Time) is 5 hours ahead of EST (Eastern Standard Time). This means when it's 12:00 PM in New York (EST), it's 5:00 PM in Dublin (IRST).
The best time to call from EST to IRST is during overlapping business hours. For EST callers, schedule between 9:00 AM - 12:00 PM EST to ensure both parties are within standard business hours.
The time difference may change during daylight saving transitions if one region observes DST while the other doesn't. Eastern Standard Time (UTC-5 (EST) / UTC-4 (EDT)) and Irish Standard Time (UTC+0 (IST) / UTC+1 (Irish Summer)) may have different DST schedules.
EST includes cities like New York. IRST includes cities like Dublin. Both time zones cover important business and cultural centers.
In 2025, DST in North America starts on March 9 at 2:00 AM and ends on November 2 at 2:00 AM. Other regions may have different DST schedules or not observe DST at all.
