Release Countdown

DateMath lists a release only once its publisher has announced a date, and takes that date from the publisher's own page, which each countdown links, with the day DateMath last checked it. Rumoured dates, leaks and release windows such as "fall" are left out. Publishers give a date, not a time, so the countdown runs to 12:00 AM on that date on your device's clock and shows the real time left, counting the hour of any daylight saving change in between. When a date moves, the countdown moves with it and the page says so.

• Your device's local time. DateMath's countdowns read the current time from your device and count to the target in your own time zone. In the US, the standard time zones are set by 15 U.S.C. 261 and daylight saving time by 15 U.S.C. 260a (from 2:00 AM on the second Sunday in March to 2:00 AM on the first Sunday in November); your device applies them. Source: 15 U.S.C. 261, 15 U.S.C. 260a.
• The Gregorian calendar. DateMath treats every date as a Gregorian date, with its leap-year rule: a year divisible by 4 is a leap year, except century years not divisible by 400, so 2000 had a February 29 and 2100 will not. Source: Gregorian calendar.

DateMath's date math is tested against more than 100 cases worked out by hand. Every worked example and table on the site is computed with the same code the calculators run, so a page and its calculator can't disagree.

Each countdown runs to a release date its publisher has announced, and each page names and links where the date comes from. DateMath checked every date below on November 1, 2026:

On November 1, 2026, GTA 6 was 18 days away. The list above counts from your own today, and when a release day passes, the release moves under Released with the days since it came out.

A release gets a page once two things are true: people search for a countdown to it, and its publisher has announced a date. A release window such as "2027" or "spring", a date from a leak, a retailer's placeholder date or a rumour is not enough, because a countdown to it would end on a day that means nothing.

• Games: the date the studio or publisher announces, such as Rockstar Games on its Newswire. Version updates of live games are left out: their dates come weeks ahead and change often.
• Films: the theatrical release date the studio lists for the US. Release dates in other countries can differ.
• Albums and tours: once an artist or label announces a date.

Release dates move: GTA 6 went from a 2025 window to May 26, 2026, then to November 19, 2026. When a publisher announces a new date, the countdown moves to it and its page says that the date changed and when it was last checked, so the number you see is never older than the source it names.

For a release that isn't listed, or a date you know that isn't public yet, the day countdown counts down to any date and time you type: name it, pick the date and copy the link to keep it.

Publishers announce a day, not an hour, so each countdown runs to 12:00 AM on the release date on your own clock, in your time zone. The tiles count real time, so the hour the clocks go back on the first Sunday in November is counted, and the calendar days line counts dates, the way you would on a calendar. A digital game can unlock at another hour in your region, and a film opens with your cinema's first showing.

For a seasonal countdown, the Christmas countdown and the season countdown count to dates that come back every year.
