Kiribati does not observe Daylight Saving Time. The country remains on its respective time zones throughout the year.

The time difference varies depending on the part of Kiribati. For Gilbert Islands Time (UTC+12), the difference is 16 hours ahead of New York City during Eastern Standard Time (UTC-5).

While few countries share the exact time zones, some Pacific Island nations like Fiji (during Daylight Saving Time) are close to Kiribati's time zones. However, Kiribati’s Line Islands Time (LINT, UTC+14) is unique as it is one of the earliest time zones in the world.
