Just looked into this and it looks like it is airing in Japan a week ahead of the rest of the globe. However, that doesn’t stop the unofficial distribution channels (🏴‍☠️ 🏴‍☠️ 🏴‍☠️) from posting the episodes prior to the global release. The AniList api that the bot uses lists the airtimes when they first are released. So, in this case, it would be the Japanese release date.
