This filter lists whoever flies each mission, meaning the company or agency that owns the rocket and runs the count. Agencies that pay for a mission and buy the ride without flying it are on the agency register instead.
Put the next 40 launches in your own calendar. It updates itself when a date moves.
A launch with a set time comes in as a timed event with a 30-minute alert. The rest come in as all-day events with no alert, and they don’t mark you as busy. A placeholder date shouldn’t interrupt your day.
It depends on how precisely the launch is filed. Every launch on this page carries a label for that. T-0 SET means the time is filed to the minute or better, so it's worth setting an alarm. ±1 HOUR is a real time, but it can be an hour out. NET ±1 DAY, ±1 WEEK or anything coarser is a placeholder and the date can move. If a launch is only filed to the week or longer, you'll see the period instead of a countdown.
FAQ / 02
BRIEF
Why do launches slip?
Usually it's weather, a clash with another user of the range, or a problem found on the rocket or payload during the count. Some missions also have a very short window. A flight to the International Space Station has to leave close to a set moment, so missing it can cost a day. Slips of a few hours or a few weeks are common and don't usually mean anything is wrong.

BRIEF
Which agencies and operators are covered?
Anyone Launch Library 2 lists. We don't filter it. That includes SpaceX, United Launch Alliance, Rocket Lab, Arianespace, Blue Origin and Firefly, state programmes like CASC, Roscosmos, ISRO and JAXA, and newer Chinese companies like Galactic Energy and LandSpace.
FAQ / 04
BRIEF
How often does this schedule update?
EveryLaunch checks the next 40 launches every 15 minutes. A scrub, a new date or a new T-0 shows up here within about 15 minutes of Launch Library 2 listing it. Later pages are checked every 12 hours, since launches that far out change less often. The countdowns don't wait for any of that. Each one runs live in your browser against the published launch time.
Launch data comes from The Space Devs' Launch Library 2. Times are UTC and mean “no earlier than”. An operator can move a launch at any point, and they often do.
