Is there any place on the internet showing the upcoming rocket launches?
Like the launches next week or next month
This website is incredibly useful, providing a list of most upcoming launches with links to livestream and information as well as keeping a list of past launches (along with some additional things like Starship info and testing dates)
Additionally; spaceflightnow.com/launch-schedule
If you want the information in a way more dense table format, you can also check out nextrocket.space.
You can also check https://www.rocketlaunch.live - It also lists the last few recent launches.
On the west coast, there's someone who maintains a mailing list called Launch-Alert announcing upcoming launches from Vandenberg AFB (and occasionally other things of interest like astronomical events).
I find the Google Calendar "Worldwide Space Launches" very useful as it integrates with my existing calendars and notifications: https://calendar.google.com/calendar/embed?src=msacpn523mpjgq0jlooh41eme4%40group.calendar.google.com
If you want super crisp, straight up launch schedule with links for more info and livestream, I might as well point you to the beautiful cards on my website - Upcoming Launches
I built it using Launch Library API which is really accurate. It's a WebApp, so just add it to your home screen and launch with a tap of a button whenever you want to know about the next launch.
I use https://www.myspaceteacher.com/Upcominglaunches/ to have a look at upcoming launches.
This is probably a bit of a late reply but I came across your post now and want to start contributing more on space.stackexchange.
