Musescore profile birthday off by 1 day

The title might be confusing, but here's what it means:
In Musescore (Website) profile settings, you are able to set your birthday in this page:
https://musescore.com/user/settings/profile
If you try to enter your birthday, ex. December 27th, and save the settings (After doing the captcha), you'll see that instead of the date, i.e. December 27th, you'll see the date one day earlier than that, i.e. December 26th.
It might be something with the time zone, because I live in Hong Kong and it's pretty much always one day earlier here than in US, so that might be why this happens.
Hope this gets fixed!
