I think it’s regarding tutorial completion, not birth date.
Maybe they’re suggesting game birthday? 
Happy Birthday! Mine’s on 2 Feb haha.
Happy birthday! This is not one of those physical or online shops where they collect your birthdate, and then send you something small (but nice) on your birthday.
Another game thanks me on my game anniversary date. I have played it close to 2 years now. Expecting the 2nd anniversary gift.
First year was 100 energy. Much appreciated.
Maybe SGG can thank players on their game anniversary date.
In the meantime, please enjoy some pixel pressies from me :
Have a great day! 
Happy birthday in advance!
Thank you so much! I’m quite surprised to see you quote the Lunar New Year Deal in SGD in the other thread. Looks like we could be compatriots.
Happy birthday hope you have a great day 
Lol I am from Singapore.
Your birthday is doubly auspicious this year. 
Let’s hope it is.
Hmmm…i wonder if you’re Alan or Joho or one of those local veterans haha.
Lol no. Low profile. Not active in EP now. More of a chill player now.
Happy birthday

Happy birthday!
You have the gift of acknowledgment from fellow humans across the planet.
I thought everyone was bots here.
Happy Birthday! and a gift full of happy thoughts 
I think it would be nice from SG to introduce some kind of rewards when you turn 1, 2, 3 or more years being in the game. Gems, flasks, items, something. It would be nice to know SG appreciate us and we’re not just numbers or atm machines to them.
Yeah…it’s a long requested item (since 1st anniversary times back in 2018)
