What time does the US market open, in your timezoneUS market hours converter: regular / pre-market / after-hours in your local time
If you're not in the US, the "open" needs converting: the regular session is 9:30 to 16:00 New York time (ET), but what that is for you depends on your timezone, and on whether the US is currently on daylight or standard time. The converter below turns regular, pre-market and after-hours into your local time and tells you whether it's trading right now.
Computed for "today" in your selected timezone, with daylight saving handled automatically. Exact pre/after-hours windows depend on your broker; US market holidays and half-days are not included, and around DST switch days go by the official source. This tool is offline and pulls no live prices.
01How the US trading day is split
In New York time (ET): the regular session is 9:30 to 16:00, where most volume and the "percent change" you see happen; the pre-market before it (typically from 4:00) and the after-hours after it (typically to 20:00) also trade, but thin and with wider spreads. Exact pre/after-hours start and end differ by broker, so go by the platform you use.
02Why your converted time shifts by an hour
The US observes daylight saving: roughly March to November it's on daylight time (EDT, UTC−4), otherwise standard time (EST, UTC−5), an hour apart. So the same "9:30 open" lands an hour differently in your local time between summer and winter. The converter uses your system's timezone data and handles this automatically, no manual adding or subtracting.
03Should you trade pre/after-hours at all
Being able to trade isn't the same as it being a good idea. Pre/after-hours has thin liquidity, wider spreads and gap risk, riskier for beginners. Before placing an order in those sessions, read can you trade pre/after hours, and what's hiding behind the "good price". Many big moves actually happen after hours (earnings, for one), which ties into earnings season.
04What this converter doesn't account for
It only does timezone conversion. It excludes: US market holiday closures (Thanksgiving, Christmas, etc.), the half-days around some holidays, and each broker's specific rules for pre/after-hours. To trade at a particular time, go by your broker's official trading calendar and session notes.
This tool is for education only; times are timezone conversions and exclude US market holidays and half-days, with pre/after-hours windows per each broker's official pages. Last updated 2026-06-20.
