Facts that change the answer

• Time zone: Asia/Tehran (UTC+3:30 in November 2026)
• Daylight saving: none; the offset stays the same all year
• Solar noon on 10 November 2026: 11:48 AM local clock time (longitude 51.42°)
• 9:00 AM on Tuesday 10 November 2026 in Tehran = 12:30 AM in New York, 5:30 AM in London, 11:00 AM in Mumbai, 2:30 PM in Tokyo
• Same 9:00 AM on 13 July 2027: 1:30 AM New York, 6:30 AM London, 11:00 AM Mumbai, 2:30 PM Tokyo

Worked example for Tehran

If both offices work 9:00 AM to 5:00 PM, Tehran and London share 12:30 PM to 5:00 PM in Tehran on 10 November 2026, when Tehran is 3 hours 30 minutes ahead of London. On 13 July 2027 Tehran is 2 hours 30 minutes ahead of London, so the shared window becomes 11:30 AM to 5:00 PM in Tehran.

On 21 December 2026 the sun rises in Tehran at about 7:09 AM and sets at 4:54 PM (9 h 44 min of daylight). On 21 June 2027 it rises at 4:48 AM and sets at 7:23 PM (14 h 34 min). Because Tehran lies about 4 minutes west of the meridian its clock is based on, solar noon falls after 12:00 by that much, before the equation of time is added.
