Lunar Festival

Hello,

I play on the Icecrown server and am wondering when the Lunar Festival will be.
I can't find any events in the Calendar between the Festival of Winter Veil that has just been in 2020/21 and the Midsummer Fire Festival in June 2021.
Will the Calendar in-game be updated with the dates of the Events before the Midsummer Fire Festival in June 2021?
According to my achievement log this should be:
- Lunar Festival
- Love is in the Air
- Noblegarden
- Children's Week

With gratitude
