Haha thank you, but it is off by one week (it's on the 19th) - must have made the mistake when I created the account.
Once your birthday has been entered, it cannot be changed. Please contact an administrator if it is incorrect.
Thanks guys! Started the day by getting some blood drawn 10 hours ago and only got home just now.
Thank you both for the birthday wishes (technically it doesn't start for another 45 minutes in my time zone)
