Five ways to have fun on a holiday weekend.

1. In theaters this weekend is “Patriots Day” Director Peter Berg’s R-rated recreation of the 2013 Boston Marathon bombing and the aftermath as police hunted for the terrorists behind it; also playing is the family friendly PG-13 flick “Monster Trucks” in which a bored teen befriends a strange and subterranean creature after building his own monster truck.

2. This Friday is the 13th and there’s no better way to celebrate than a marathon of your favorite scary movies.

If you have a cable TV subscription, tune into the Syfy channel to watch their marathon of Freddy Krueger and Jason films. Or head to the theaters to see “The Bye Bye Man” PG-13, a mysterious figure that is the root cause of the evil behind man’s most unspeakable acts.

3. January may be one of the coldest months of the year, but it’s also National Walk Your Dog Month. Walking your dog is good for any number of reasons. It provides an outlet for their energy, provides physical and mental stimulation and social interaction.

Regular walking can lengthen and improve the quality of life for your dog and help you shed those extra holiday pounds. Grab the leash and get walking.

4. This weekend is the NFL playoffs’ divisional playoffs, so you’ve got two football-filled days to look forward to. On Saturday, the Seahawks play the Falcons at 4:35 p.m. EST on Fox and the Texans square off against the Patriots at 8 p.m. EST on CBS.

On Sunday, the Steelers face the Chiefs at 1:05 p.m. EST on NBC and the Packers play the Cowboys at 4:40 p.m. EST on Fox. Visit nfl.com for more information.

5.While MLK Day is celebrated on Monday, Martin Luther King Jr.’s actual birthday is on Sunday. King was the chief spokesman for nonviolent activism in the Civil Rights Movement, which protested racial discrimination in federal and state law.

In 1994, President Bill Clinton signed into law the King Holiday and Service Act, which challenges Americans to make MLK Day a day of citizen action volunteer service in honor of King. Find out more about King and opportunities to volunteer at mlkday.gov.
