The boys of DAY6 are back and ready to rock!

On July 15, the JYP Entertainment band released their fifth mini album 'The Book Of Us: Gravity,' featuring energetic title track "Time Of Our Lives."

"Time Of Our Lives" is an energetic pop track celebrating the present, reminding listeners to stop worrying and have fun creating good memories. In the video for the track, all five members are seen in a number of fresh and colorful angles, the camera fluidly moving from one set to the next to create an atmosphere as eye-catching as it is frantic.

Meanwhile, following promotions for the album, DAY6 will be heading out on their 2019 'Gravity' world tour, beginning in Seoul on August 9-11 before heading out to 26 different cities in Asia, North America, Australia, and Europe.
