Just a quick question : is the count down for EU correct?
According to google 5pm CEST is 5 pm in my local time, but the counter suggest that it is 6pm local time.
Could perhaps be daylight savings, we dont have that locally.
In the announcement they wrote 5pm CEST because when they announced it 3-4 weeks ago it was still summer time. It's now CET. Seasons have always started at 5pm so there's no reason to believe they stay at imaginary summer time and start season an hour later than the last 11 ones...
I think the devs are too busy with fixing up the other tools that depend on API, which usually changes around this time as well
I've poked them in the past, but since as you noted it was missing the last few seasons I've decided to add it to my homepage. I honestly don't know why it's not on every website, on Reddit, on the official Diablo 3 page, and in the launcher. A countdown script takes 2 minutes to create and is so awesome (and necessary, a friend of mine once almost came an hour late to season start).
Maybe they'll add it, I'll poke again, but in the meantime feel free to go to my website ;-) (I do not have any ads or get any revenue or anything for clicks, so I literally couldn't care less, but the more people visit the more inclined I am to keep it up, as I have really limited time these days.)
