Six Flags Entertainment (SIX)  will now open its Southern California flagship property Magic Mountain every day of the year starting January 1, 2018.

The park had previously been open daily in peak season during the spring and summer and only on weekends and holidays during the off-season. Six Flags said it'll "have an operating calendar on par with all the other theme parks in Southern California," including Walt Disney Co's  (DIS) Disneyland, Comcast's (CMCSA) Universal Studios, Cedar Fair's (FUN) Knott's Berry Farm and SeaWorld Entertainment's (SEAS) San Diego park.

Magic Mountain, which hosts 47 million visitors annually, already holds "Fright Fest" at Halloween and "Holiday in the Park" during winter holidays, but plans to add new events for the additional 100 days it'll be open starting next year.

Six Flags stock traded up 1.1% to $52.86 late Thursday morning.
