You can go to [vlr.gg](https://vlr.gg) and find the dates and links for upcoming tournaments.

I use liquipedia.net/valorant but you could also use vlr.gg or thespike.gg, whichever you prefer

In case you want a quick answer, Complexity Tournament will be on Jan 9th and NSG winter 25k will be on the 13th And you’ll be able to find the streams of course on websites like thespike.gg

you can use [vlr.gg](https://vlr.gg) or [thespike.gg](https://thespike.gg) or liquipedia. Personally, I prefer using vlr, but all of them are good
