[2019] Why does Riot release everthing in NA time now?

Seriously it's kind of annoying to always check timezones and add a day to event dates because Riot thinks NA is their only region. Why can't Riot just release stuff separately for every Server? I was hyped for URF but now I gotta wait one more day :/

Edit: I phrased it badly. My complaint is not that we have half a day less of event times and we get stuff a lot later due to the time. My problem is the fact that Riot doesn't care about giving out the necessary information. I know so many people that read "URF on 28th" and took a day off. The misadvertising is the problem here.
