It's a day made by me that every one comes together to eat a potato for world hunger and if you eat a potato you donate a potato

A day where sisters all get together and go shopping, exchange gifts and have a meal together while sharing childhood stories about the times they were kids and take photos of that day

I think for the the birthday count down me personally i think there should be a place where you could put the time you were born so you could have the exact countdown. That would be really nice.
