Synchronized Global Release (SGR) allows everyone with a Musician Plus or Ultimate plan to choose a custom release time in Spotify. If you want, you can even release your music simultaneously in every country — at the exact same time!
Keep in mind, if you choose 12:00 AM EST, it'll still be the day before in a handful of countries. For example:
Spotify shows the date of earliest time zone your release will go live in, so it might look like it's being released early, but it's just being released at the time you requested around the world at the same time!
To check various time zones around the world, something like this website may come in handy.
