Standard year-round offset: Tel Aviv is 7 hours ahead of Montreal in both winter (EST UTC-5 → IST UTC+2) and summer (EDT UTC-4 → IDT UTC+3). When it is 9:00 AM in Montreal, it is 4:00 PM IST/IDT in Tel Aviv. Best meeting window: 9:00 AM – 12:00 PM EST/EDT in Montreal (4:00 PM – 7:00 PM IST/IDT in Tel Aviv — Morning/Evening Shoulder Bridge).
The standard baseline difference between Montreal (Canada) and Tel Aviv (Israel) is 7 hours (Tel Aviv ahead of Montreal) in both winter (EST UTC-5 vs. IST UTC+2) and summer (EDT UTC-4 vs. IDT UTC+3). Because Canada and Israel change Daylight Saving clocks on different Sundays, the offset temporarily shifts to 6 hours during a 12-day spring gap (Mar 14, 2027 – Mar 26, 2027) and 3-day autumn gap (Oct 31, 2027 – Nov 3, 2027).

The standard time difference is 7 hours (Tel Aviv ahead of Montreal) in both winter (EST → IST) and summer (EDT → IDT). It temporarily shifts to 6 hours during the 12-day spring gap (Mar 14, 2027 – Mar 26, 2027) and 3-day autumn gap (Oct 31, 2027 – Nov 3, 2027).
No — at 4:00 PM EST/EDT in Montreal, it is 11:00 PM IST/IDT (same day) in Tel Aviv, which is after the 9:00 PM evening cutoff. Schedule earlier during 9:00 AM – 12:00 PM EST/EDT (4:00 PM – 7:00 PM IST/IDT in Tel Aviv).
Aim for 9:00 AM – 12:00 PM EST/EDT in Montreal, which is 4:00 PM – 7:00 PM IST/IDT in Tel Aviv (1h/day of 9–5 overlap). Avoid calling between 2:00 PM – 7:00 AM EST/EDT (+1 day) in Montreal (9:00 PM – 2:00 PM IST/IDT (+1 day) in Tel Aviv), when at least one city is outside 7:00 AM – 9:00 PM.
Montreal: Sun, Mar 14, 2027 (EST → EDT, new gap: 6 hours (EDT UTC-4 vs IST UTC+2)). Tel Aviv: Fri, Mar 26, 2027 (IST → IDT, new gap: 7 hours (IDT UTC+3 vs EDT UTC-4)).
Because Tel Aviv officially operates on a Sunday–Thursday workweek (Friday–Saturday weekend) while Montreal 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 (1h/day overlap in winter; 1h/day in summer).
