US Stock Time — Market Hours

Is the US market open right now?

New York trades while much of the world sleeps, and the answer moves twice a year when daylight saving time shifts. US Stock Time works out the current state of the market and counts down to the next change — in your own time zone.

■ What it does

・Tells you the market's state at a glance
Regular hours (MARKET OPEN), pre-market, after-hours, closed, holidays and half days, each in its own colour. Six possible states, one look.

・Counts down to the next open or close
Hours, minutes and seconds. During the session it runs to the closing bell; when the market is shut it runs to the next open.

・The home screen widget counts down every second
Android widgets normally refresh no more than twice an hour. This one uses a view that keeps its own time, so the countdown on your home screen ticks down second by second without opening the app.

・Handles daylight saving time for you
EDT and EST are detected automatically. The app shows Eastern time alongside your local time, so there is nothing left to convert in your head.

・A 24-hour dial shows where you are
Pre-market, the regular session and after-hours are drawn as arcs on the dial, with a marker at the current moment, and the screen takes on the color of the market's current state. You can see how far off the open is without reading a number.

・Holidays and early closes are calculated, not listed
Independence Day, Thanksgiving, Christmas, Good Friday and the rest, plus the half days that close at 13:00 ET — the day after Thanksgiving, Christmas Eve, the day before Independence Day. The next holiday and the next early close are always on screen.

・Market holiday calendar
See this year's and next year's holidays and early closes in one list — handy for planning weeks or months ahead.

・Alerts before the open, on holidays and on early closes
Get a heads-up about 15 minutes before the open on trading days, on market holidays and on early-close days. Every alert is off by default; turn on only the ones you want.

・A conversion table for the sessions
Pre-market, regular and after-hours, given in Eastern time and in your local time, for both summer and winter.

・Landscape layout
Turn the phone and the display becomes two columns with larger figures — readable from across a desk.

■ Who it is for

・Anyone holding US equities from outside New York
・Anyone who does not want to miss an earnings call or a jobs report
・Anyone tired of looking up whether daylight saving has started
・Anyone who just wants to know how many hours are left before the open

■ One small ad, and nothing sent to us

A single small banner ad sits at the bottom of the screen; the "Remove Ads" in-app purchase removes it. Widgets and notifications never show ads, and there are no affiliate links. If you have been using the app since before version 1.2.1, you will not see ads.

Trading hours are worked out from the date arithmetic on your device, so that part of the app never talks to the network, and nothing is sent to our servers. No account is needed.

The ad is served by Google AdMob, which receives information such as your advertising ID in order to show it. In the EEA, the UK and some other regions, you are asked for consent first.

"Support" (the optional tip jar) and "Remove Ads" talk to Google Play only to process the purchase.

It requests two permissions. "Receive boot completed" rebuilds the widget's countdown and the alert schedule after you restart the phone, and shows no prompt. "Notifications" is asked for only when you turn on one of the alerts (all off by default).

■ Please note

This app reports exchange business hours. It is not investment advice. Trading hours can change with US holiday legislation or by decision of the exchanges. Check the hours published by your own broker before trading.
