When the US shifts to EDT in spring, the offset shrinks to 9 hours and 30 minutes. That 6 AM Eastern standup then lands at 3:30 PM IST. India’s clock never changes, so the full seasonal swing rests on the US side. Teams that schedule meetings at the boundary of the overlap window should adjust their recurring invites in March and November.
