I figured this was going to happen last week, but it was only a few days ago that crunchyroll announced that they were going to host Makoto Shinkai's three major works for streaming for free for the 24 hours that Global Shinkai Day will last (Friday (2/27) from 5 pm/PST to Saturday (2/28) 5 pm/PST). So I'm late that even Anime News Network had covered this yesterday, just been a very busy time between work, trying to prepare a few things for GSD, and other responsibilities.
There's a group made on crunchyroll for this event. Click here or on the banner below to go to it.
