India Standard TimeTimes assume the exchanges’ regular sessions and are converted from exchange local time to India Standard Time; holidays and early closes can remove the overlap on a given day.

| LSE | 13:30 | 22:00 |
| NASDAQ | 15:00 | 21:30 |
How the LSE–NASDAQ overlap is calculated
The overlap is the intersection of each exchange’s regular trading session after converting both to India Standard Time. In this timezone, LSE runs 13:30–22:00 and NASDAQ runs 15:00–21:30, so both are open together from 20:00 to 22:00 — 2h of shared trading time.
Weekends are excluded, and any full-day holiday or early close on either side shrinks the window for that date. Use the two holiday calendars below before planning a session that relies on the overlap, and check the live open/closed status if you need the current figure rather than the scheduled one.
