The carefree days of summer are long gone, but that doesn't mean you can't find special ways to spend time together as a family.

Although the month starts out strong with Labor Day, who's to say that the fun has to stop there? In fact, there are plenty of other September holidays, observances and awareness day to help your family start the school year on a celebratory note.

Perhaps, that means using holidays like National Read a Book Day (a Read With Jenna book, perhaps?) and National Girls’ Night In Day as an excuse to block out a day for some much-needed R&R. Or if your idea of fun is indulging in your favorite foods, then celebrate the days that revolve around chocolate milkshakes, cheese pizza and guacamole.

And, let's face it, parents need all the help they can get at the start of the school year. Get your kids creative juices flowing by observing wacky (and wonderful) holidays like National Play-Doh Day, Talk Like a Pirate Day and Make a Hat Day.

Speaking of family, September's holiday and awareness days are all about spreading the love. Grandparents get their own holiday this month, and Love Note Day is the perfect occasion pen a heartfelt note to someone who makes your heart skip a beat. Your pets should feel the love, too: Hug Your Hound Day, National Pet Bird Day and Ginger Cat Appreciation Day all nod to our best furry and feathered friends.

Now, add these special dates to your calendar to embrace all that September has to offer.
