Marc Cherry has stated that the five-year-jump was a method they came up with in order to explore new areas, new stories, and the producers weren't gonna "futurize" the series, which is why there is no reference of the year they're living in.

But it is odd, particularly considering that, according to what Angie said in 6.09, Danny was born in either 1991 or 1992, and he was 18 years old. Julie was born somewhere in 1990, and thanks to the time jump, she's 25 now. So it's like they completely discarded the timeline prior to the jump. Every character who appeared before the time jump aged five years. Every character who appeared afterwards, well, it's like they never experienced that jump themselves. Weird...
