Just Because Day has arrived on Monday this year, marking a time for people to practice positive attitudes.

Each year on Aug. 27, the holiday celebrates spontaneity as well as doing above and beyond what is expected of us: for example, one could hold a door for someone and also tell him or her to have a great day.

Moreover, Just Because Day offers the opportunity to do something you want to despite there being no reason or logic behind doing it. The unexpected activity or action will invigorate a fresh and positive attitude, making the holiday one worth celebrating.

Often times, participating in an uncommon or last-minute activity significantly adds to the fun of it. Acting "on a whim" or "just because" may also bolster self-confidence and provide a chance to finally do something you have been meaning to do.

Suggestions for Just Because Day include a variety of fun things to do today.

With the holiday falling toward the end of summer, an unplanned trip to a nearby beach would be a great way to spend Just Because Day. If visiting a beach is too difficult, enjoy fun in the sun at a pool or lake.

Also on Aug. 27, many people take the opportunity to visit someone they have not seen in a long time. Perhaps even try a new recipe and share the food with someone during the surprise visit.

Just Because Day can also be a good time to show your partner or other loved ones how you feel about them. Share a nice sentiment in a card or call a family member to see how they are doing and remind them that you care.

Essentially, the holiday encourages people to go outside of ordinary routine in order to increase overall happiness.

On Twitter, many users are talking about their Just Because Day plans.

"Happy 'Just Because' Day," wrote CPFS. "We think we should thank our troops and veterans for their service everyday."

"We really CAN make each day special," wrote Adam. "It's a choice."
