FAQ
- DO you need to watch all the concert?
No, you do not need to watch all of it. They will be the same music but the only difference is who will be the performers. If you want to see your favorite artist from Japan than you would wait until concert #2 starts.
- Where can i watch it?
Youtube or Twitch
- Will i be able to watch it if i miss it?
I do not know the answer
- How will i know when it starts or other time problems?
Lucky i made countdowns to each event

Miku Expo #2: https://www.timeanddate.com/countdown/vacation?p0=248&iso=20210606T17&msg=Miku%20expo%20%232

As for the question to which time is best for each location, my best understanding is:
Asia/Pacific Ocean/Russia location would be 1 and 2
EU/Africa location would be 2 and 3
US/Latin location is 3
America/Mexico/Canada could in theory watch the 1st one but you have to be staying awake. That goes the same with EU and Africa where people should be sleeping.
