National Girlfriend Day or National Girlfriends' Day 2016 is a special day to honour the woman/women you love. On this day, men acknowledge the woman they admire and single ladies rejoice in their sisterhood.

For many women, this day calls for a girls' night out or a night in.

Although its origin is not known, National Girlfriend Day is a special occasion that strengthens bonds, fosters trust and helps in spreading more cheer among people who are blessed with love and a wonderful group of friends.

If you want to make your girlfriend feel special on this day (Aug. 1), then you could update your status message on Facebook or tweet about your partner.

But if this activity sounds like a daunting task, here are a few messages that can make your better half or girlfriends happy.

You are a super amazing woman. You are my confidant, my mentor, my strength and my best friend. I thank God for giving me the best girl pal.

Life cannot be complete without a friend like you who is always there to share pizza, listen to stupid stories, share heartbreaks and help me get back to life. I love you.

If there's one thing on earth I never wanted to end, its loving you.

The shortest definition of happiness is YOU

The shortest definition of love is YOU

The shortest definition of togetherness is YOU

The shortest definition of my life is YOU

You will always be my only choice whether it is a GF day or not.

It's love when you can be goofy and scruffy, and still be hugged as if you were the most attractive human being on the planet.

The sunrise may be perfect, because of its beautiful hues. But my life is perfect, because I have you.

I am very selfish about the things that I want, and the thing that I want most desperately is your happiness.
