Five ways to have fun this weekend.

1. It is the weekend of the biopic, first with the PG-13 drama “Marshall” about Thurgood Marshall, the first African-American Supreme Court Justice; “Goodbye Christopher Robin” a PG-13-rated look at the life of “Winnie the Pooh” author A.A. Milne and the creation of stories inspired by his son C.R.’s stuffed animal collection.; and “Professor Marston and the Wonder Women” about psychologist and “Wonder Woman” creator William Moulton Marston, his polyamorous relationship with his wife and mistress and the controversy his comic generated. If you rather watch action or horror, check out the PG-13 horror film “Happy Death Day” about a college student forced to relive the day of her murder until she discovers her killer’s identity; and “The Foreigner” rated R and starring Jackie Chan as a businessman with a buried past who seeks justice when his daughter is killed in an act of terrorism.

2. It’s not only October but also Friday the 13th! Make it a fun night of watching scary movies (such as those from the “Friday the 13th” franchise), eating special spooky treats (black cat cookies, anyone?) or reading a scary tale around a fire.

3. National Chess Day is on Oct. 14 this year. This Saturday, take part by playing chess with friends in person or online, and check the newspaper to see if any chess clubs are holding any events this weekend.

4. Saturday is also National Dessert Day, celebrate by making your favorite sweet treat or going out to a restaurant and ordering dessert first!

5. Try not to be too miserable on Sunday even though it is National Grouch Day. Celebrate it by sharing your favorite Grumpy Cat memes or watching episodes of Sesame Street featuring Oscar and his family of grouches.
