How the Market Time Zone Converter Works
Financial markets operate across different time zones. A timestamp that shows 10 AM in one time zone may be after hours in another. This converter takes a Unix epoch timestamp and displays the corresponding local time for four major stock exchanges: NYSE in New York, LSE in London, SSE in Shanghai, and TSE in Tokyo. Paste Unix timestamp 1704067200 to see NYSE closed on New Year holiday while UTC shows midnight January 1. Always verify exchange holiday calendars for trading decisions. Holiday calendar separate from clock conversion; closed days still convert timestamps accurately. JavaScript Date.now millisecond timestamps need division by one thousand before Unix second conversion.
Each market card shows the local date and time, the regular trading hours, and a clear open or closed status indicator. The status is calculated by checking whether the local time falls within the exchange's trading session on a weekday. The tool also shows the UTC time and your device's local time for reference. Overlap between NYSE and LSE from 13:30 to 16:00 UTC often produces highest liquidity for transatlantic equity flow. JavaScript Date.now millisecond timestamps need division by one thousand before Unix second conversion. NYSE regular session nine thirty to sixteen zero zero Eastern anchors most US equity bar alignment.

Market Time Conversion
Local Time = Intl.DateTimeFormat with timeZone per market
NYSE: 09:30-16:00 ET weekday - America/New_York
LSE: 08:00-16:30 GMT weekday - Europe/London
SSE: 09:30-15:00 CST weekday - Asia/Shanghai
TSE: 09:00-15:00 JST weekday - Asia/Tokyo
Status = week day and within trading hours
Daylight saving time is handled automatically by the Intl.DateTimeFormat API. The tool uses your browser's local timezone support for accurate conversions. Extended hours and pre market sessions are not modeled. Status reflects regular session hours only. JavaScript Date.now millisecond timestamps need division by one thousand before Unix second conversion. NYSE regular session nine thirty to sixteen zero zero Eastern anchors most US equity bar alignment.

FAQ
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 at 00:00 UTC. It is a standard way computers represent time. Financial APIs often return timestamps in Unix format which this tool converts into human readable market times. Financial APIs from Alpha Vantage, Polygon, and Yahoo return Unix timestamps in seconds or milliseconds. Divide milliseconds by 1000 before entering here. Daylight saving spring forward hour requires logging whether API timestamp is UTC or exchange local.
Are holidays considered for market status?
This tool checks weekdays and trading hours but does not include exchange holiday calendars. A market may show as open on a weekday that is actually a holiday. Check exchange holiday schedules separately for critical trading decisions. Good Friday and US federal holidays close NYSE even when the weekday check shows open status in this tool. Pre market four zero zero Eastern and post market twenty zero zero extend beyond regular session flags. Holiday calendar separate from clock conversion; closed days still convert timestamps accurately.
What are the best market overlap periods?
The most active overlap is between NYSE and LSE from 13:30 to 16:00 UTC (09:30 12:00 ET / 14:30 17:00 GMT). Another overlap is LSE and SSE from 08:00 to 09:30 UTC. TSE overlaps with SSE from 01:00 to 06:00 UTC. Overlap periods typically have higher liquidity and volatility. Tokyo and Shanghai sessions overlap briefly, affecting Asian ADR pricing and overnight US futures reaction. Holiday calendar separate from clock conversion; closed days still convert timestamps accurately. JavaScript Date.now millisecond timestamps need division by one thousand before Unix second conversion.
Can I use this for forex market hours?
Forex markets trade 24 hours a day on weekdays. However the most liquid sessions correspond to the overlap of major exchange hours. The tool helps you identify when each major financial center is active. Forex liquidity peaks during London and New York overlap even though forex trades continuously on weekdays. JavaScript Date.now millisecond timestamps need division by one thousand before Unix second conversion. NYSE regular session nine thirty to sixteen zero zero Eastern anchors most US equity bar alignment. Daylight saving spring forward hour requires logging whether API timestamp is UTC or exchange local.
How does daylight saving time affect the conversion?
The Intl.DateTimeFormat API automatically adjusts for daylight saving time in each timezone. For example NYSE switches between EST (UTC 5) and EDT (UTC 4). The trading hours remain 09:30 16:00 local time but the UTC offset changes. Daylight saving shifts UTC offsets twice yearly but local exchange hours stay constant in local time. NYSE regular session nine thirty to sixteen zero zero Eastern anchors most US equity bar alignment. Daylight saving spring forward hour requires logging whether API timestamp is UTC or exchange local.
