How Many Trading Days

We follow the standard NYSE/Nasdaq holiday schedule: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. When these fall on a weekend, an observed weekday holiday is used instead. The list above shows the holidays still ahead this year.

Yes — beyond the scheduled holiday calendar, U.S. markets have closed 11 times since 1990 for emergencies and national days of mourning: four days after the September 11 attacks, two days for Hurricane Sandy in 2012, and single days honoring Presidents Nixon, Reagan, Ford, George H. W. Bush, and Carter. Our historical counts account for all of them.

Scheduled early-close sessions — such as the day after Thanksgiving, Christmas Eve in some years, or the day before Independence Day — end at 1:00 p.m. ET and are counted as 0.5 trading days. That's why the counter sometimes ends in .5: at least one remaining session is an early close.

If today is a weekday and U.S. markets are open, we count it as a trading day until 4:00 p.m. Eastern Time (the normal close). After 4:00 p.m. ET, today is treated as finished and no longer included in the remaining-days count. If today is a weekend or full-day market holiday, it is not counted.

This site is based on regular-session hours for the major U.S. equity exchanges (such as NYSE and Nasdaq) and uses U.S. Eastern Time. It does not track extended hours, futures markets, or cryptocurrencies.
