how do i have the birthdays of my contacts show up on my google calendar (and in my calendar widget). When i access my calendar online, they are not visible either. Also, i noticed that in the contacts on my phone, the birthdays are visible, but when i look online, they are not. how could this be if i sync between my phone and google account? also, sometimes when i performa sync, i get an error message saying "delete limit exceeded. there are x deleted items for calendar....."
