Israel Switches to Winter Time, Affecting Daylight Hours
Translated & summarized from Cursorinfo by baba
Israel will switch to winter time on October 25, 2026, moving clocks back one hour from 02:00 to 01:00. This change will result in earlier sunrises and sunsets, with darkness falling sooner in the afternoon. The transition is part of a legal framework to align daily schedules with natural daylight. Israel's national time is maintained by atomic clocks and synchronized with international standards.

- Israel will switch to winter time on October 25, 2026, moving clocks back one hour.
- The time change will cause earlier sunrises and sunsets according to official clocks.
- Winter time will be in effect until March 26, 2027, when summer time resumes.
- The purpose is to align human activity with natural daylight patterns.
- Israel's national time is determined by cesium atomic clocks and synchronized globally.
- During winter, Israel's time zone is UTC+2.
In the early hours of Sunday, October 25, 2026, Israel will transition to winter time, setting clocks back by one hour. This change, mandated by law, will see the clocks move from 02:00 to 01:00, granting residents an extra hour of sleep that night. The switch aligns with Israel's established time-change regulations, marking the end of the 2026 summer time period, which began on March 27, 2026. Winter time will remain in effect until March 26, 2027, when clocks will again advance by an hour for summer time.
The shift to winter time will result in earlier sunrises and sunsets according to official clocks. For instance, on October 25, sunset in Tel Aviv is expected at 16:57, a full hour earlier than the previous day's 17:58. Similar earlier sunsets will occur in Jerusalem, Haifa, and Beersheba. While mornings will become lighter sooner, darkness will descend earlier in the afternoon, potentially impacting those who finish work around 17:00. It is important to note that the clock change does not alter the actual duration of daylight but rather shifts its timing relative to the daily schedule.
The Ministry of Economy and Industry explains that the purpose of these time changes is to synchronize human activity with natural daylight patterns. Summer time maximizes evening natural light, while winter time brings earlier daylight hours. The reduction in sunlight exposure during winter months can affect mood and alertness, with hormones like melatonin and serotonin playing roles in regulating sleep and mood, though individual responses vary.
Israel's precise timekeeping relies on a sophisticated system at the National Physical Laboratory, overseen by Dr. Oleg Popov. The laboratory utilizes three cesium atomic clocks to establish the national time standard, designated UTC(INPL). This standard is synchronized with international laboratories by comparing measurements 86,400 times daily, ensuring consistency with Coordinated Universal Time (UTC). During winter, Israel's time is UTC+2, and during summer, it is UTC+3. This accurate time reference is crucial for various civil and commercial systems, including broadcasting and telecommunications.
