Like if your birthday was 1 and you add a social connect, twitter or website or what ever, and update; then your birthday is 3. Even if you make no change to anything, but just hit update (as an example), yet still your birthday is now 5.
Just a funny quirk I noticed. May just be my browser Firefox Quantum 64.0 or my UbuntuMate 18.04. Or may be happening for everyone? :P

Another crew member reported this same issue recently. Prior to that time, I had never bothered trying to enter my birthday. When I eventually did, I got the same +2 day problem.
Pressing Update seems to work like advancing a clock forward in increments of 2 days. I ended up setting the month back to December, then just kept pressing Update to advance it every 2 days until I reached my correct birthday of January 22.
But your birthday entered here is not visible to others. I only know of members' birthdays because they have personally mentioned the dates in-game, and I have written them down. :)
