My Birthday Bonus SC!

My birthday is coming up on the 10th, and most of all I'm looking forward to getting my free bday bonus SC from all my verified casinos! Do I need to contact the casino on my bday and let them know? Or do they automatically add it to your account? Do you have a list of the casinos who give a bday bonus, the amount of bonus, and if they have any requirements to get your bonus such as email support a reminder, or live chat if available? I missed out on most of them last year because I didn't know that so many offered a bday gift. I remember seeing the total amount you received on your bday! It's worth the extra effort, I want to get an early start. Thanks to all who share any personal knowledge or experience about bday bonuses. And thank you for your time.
