How can I change the date of birth on my ecommerce account?

Thanks a lot for the feedback. Really appreciate it a ton, will be adding the shipping policy as well as updating some of the media and color schemes to make it look more appealable.

Extra note, I can’t seem to delete or edit the previous post I made where I posted my email, though I don’t mind any extra feedback or if you can even maybe help delete it for me, thanks again. - Travele
