Standard year-round offset: Tel Aviv is 2 hours ahead of London in both winter (GMT UTC+0 → IST UTC+2) and summer (BST UTC+1 → IDT UTC+3). When it is 9:00 AM in London, it is 11:00 AM IST/IDT in Tel Aviv. Best meeting window: 9:00 AM – 3:00 PM GMT/BST in London (11:00 AM – 5:00 PM IST/IDT in Tel Aviv — Golden 9–5 Overlap).
The standard baseline difference between London (United Kingdom) and Tel Aviv (Israel) is 2 hours (Tel Aviv ahead of London) in both winter (GMT UTC+0 vs. IST UTC+2) and summer (BST UTC+1 vs. IDT UTC+3). Because United Kingdom and Israel change Daylight Saving clocks on different Sundays, the offset temporarily shifts to 3 hours during a 2-day spring gap (Mar 26, 2027 – Mar 28, 2027).

The standard time difference is 2 hours (Tel Aviv ahead of London) in both winter (GMT → IST) and summer (BST → IDT). It temporarily shifts to 3 hours during the 2-day spring gap (Mar 26, 2027 – Mar 28, 2027).
It works for a late-day check-in: 4:00 PM GMT/BST in London is 6:00 PM IST/IDT (same day) in Tel Aviv, which falls in Tel Aviv's evening shoulder window before the 9:00 PM cutoff.
Aim for 9:00 AM – 3:00 PM GMT/BST in London, which is 11:00 AM – 5:00 PM IST/IDT in Tel Aviv (6h/day of 9–5 overlap). Avoid calling between 7:00 PM – 7:00 AM GMT/BST (+1 day) in London (9:00 PM – 9:00 AM IST/IDT (+1 day) in Tel Aviv), when at least one city is outside 7:00 AM – 9:00 PM.
London: Sun, Mar 28, 2027 (GMT → BST, new gap: 2 hours (BST UTC+1 vs IDT UTC+3)). Tel Aviv: Fri, Mar 26, 2027 (IST → IDT, new gap: 3 hours (IDT UTC+3 vs GMT UTC+0)).
Because Tel Aviv officially operates on a Sunday–Thursday workweek (Friday–Saturday weekend) while London works Monday–Friday (Saturday–Sunday weekend), there is 0 hours of standard business overlap on Fridays and Sundays. Schedule recurring team calls Monday through Thursday (6h/day overlap in winter; 6h/day in summer).
