A Christmas Tidbit from Ellery

Els is chatting with my mom on the phone today and mom was asking her about Christmas.  After answering some questions, she paused and said, "Nanna, how did you know it was Christmas here?"  Nana says, "it's Christmas, too. It's Christmas all over the world."  Another pause from E.  "It is" she says?  "I didn't know that."  Nana says, "Yes, everywhere. Call Goggy and ask him if he is having Christmas there, too."  Ellery says, "huh? It's Christmas in Anchorage too?"
