Market overlap
JPX Tokyo vs NSE India overlap
Compare the next common trading window between Japan Exchange Group and National Stock Exchange of India, including local times in both markets and the UTC overlap block.

Workflow examples
Practical ways to use the JPX Tokyo / NSE India overlap
The overlap page is for calendar and operations planning. It should help teams schedule monitoring, handoffs, and source checks without drifting into investment advice.
Closure pre-check workflow
Before scheduling a recurring cross-market ritual, check JPX Tokyo: Labor Thanksgiving Day (Mon, Nov 23, 2026) Then check NSE India: Christmas Day (Fri, Dec 25, 2026)
Half-day and notice workflow
If the overlap matters for publishing, ops, or compliance timing, check half-day sensitivity first: JPX Tokyo: No modeled half-day appears in the current catalog window. NSE India: No modeled half-day appears in the current catalog window.
Overlap pair read
JPX Tokyo and NSE India: why this pair is different
The same overlap length can hide important differences. This read exposes the pair-specific clock relationship, session denominator, source boundary, currency split, and whether the common window is deep enough to be useful.
Pair fingerprint
JPX Tokyo vs NSE India is a cross-country · different currencies · partial overlap comparison. JPX Tokyo uses Asia/Tokyo; NSE India uses Asia/Kolkata. The overlap has to be read through two exchange-local clocks, not a fixed UTC offset.
Overlap strength
2h 45m of shared regular-session time equals 50% of the shorter modeled regular-session day. UTC window: 03:45 to 06:30 UTC.
Local-market reading
JPX Tokyo sees the overlap as 12:45 PM to 03:30 PM GMT+9; NSE India sees it as 09:15 AM to 12:00 PM GMT+5:30. This is the important distinction from a generic “markets open now” list.
Session denominator
JPX Tokyo models 330 regular-session minutes per trading day; NSE India models 375. The overlap percentage is based on the shorter of those two regular-session totals.
Source boundary
Regular sessions and full-day closures come from JPX domestic trading hours and NSE market timings. The page does not model half-days, auctions, lunch-break changes beyond the stored sessions, halts, circuit breakers, or emergency exchange notices.
Currency and venue context
JPX Tokyo is denominated in JPY; NSE India is denominated in INR. This page helps with schedule overlap, not relative value, liquidity, or trade recommendations.
A strong schedule overlap is still not a trading recommendation. It only means the modeled regular sessions share minutes after timezone conversion and tracked full-day closures are skipped.
Calendar watchlist
JPX Tokyo and NSE India: closures, half-days, and DST checks
A pair can look similar to another pair if you only compare the overlap minutes. The practical reading depends on whether the exchanges share a timezone, whether one side has an upcoming closure or half-day, and how much of the shared window survives after both regular-session calendars are applied.
Timezone drift watch
JPX Tokyo is UTC+09:00 in Asia/Tokyo; NSE India is UTC+05:30 in Asia/Kolkata. Recheck the page around DST transition weeks because one side can move while the other does not.
Next full-closure check
JPX Tokyo: Labor Thanksgiving Day (Mon, Nov 23, 2026) NSE India: Christmas Day (Fri, Dec 25, 2026) The overlap skips modeled full-day closures, but unusual exchange notices still belong to the official calendars.
Half-day sensitivity
JPX Tokyo: No modeled half-day appears in the current catalog window. NSE India: No modeled half-day appears in the current catalog window. Half-days can shorten or remove the practical overlap even when the regular-session model says both markets are open.
Coordination pattern
partial overlap: The shared window is 2h 45m, enough for scheduled monitoring but still narrow enough to verify closures first.
Session shape
JPX Tokyo has a split regular session, so the overlap grid should be read as separate open blocks rather than one continuous day. JPX Tokyo is anchored in Japan; NSE India is anchored in India. Cross-country pairs need both calendars checked.
Currency boundary
JPX Tokyo is denominated in JPY, while NSE India is denominated in INR; schedule overlap does not imply currency or liquidity equivalence. This page is a calendar and timezone reference only, not a trading signal or investment comparison.
Use the watchlist as a pre-check before relying on the overlap for publishing, operations, settlement planning, or live market monitoring. It still does not replace the official exchange notice feeds.

Caveats
The overlap calculation skips tracked full-day closures, but it does not promise that both exchanges are tradable through half-days, auctions, lunch extensions, halts, or emergency notices.
