Aim for 11:00 AM – 5:00 PM IST/IDT in Tel Aviv, which is 9:00 AM – 3:00 PM GMT/BST in London (6h/day of 9–5 overlap). Avoid calling between 9:00 PM – 9:00 AM IST/IDT (+1 day) in Tel Aviv (7:00 PM – 7:00 AM GMT/BST (+1 day) in London), when at least one city is outside 7:00 AM – 9:00 PM.
Tel Aviv: Fri, Mar 26, 2027 (IST → IDT, new gap: 3 hours (IDT UTC+3 vs GMT UTC+0)). London: Sun, Mar 28, 2027 (GMT → BST, new gap: 2 hours (BST UTC+1 vs IDT UTC+3)).
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).
