Jenna has always lied about her age, but tonight there was yet another episode where she has a birthday. I wanted to check if it was in the same month. Last season, it was in the March 5, 2009 episode "Goodbye, My Friend" where everyone gives Jenna's birthday to Tracy. But tonight's episode Jenna suspected her mother forgot her birthday but in reality had a big party for her. It's February 4th, but its excusable since in TV it isn't always the month the episode airs. And they were close in time anyway.
