If you could time travel to any era, where and when would you go?

If I would time travel to any Era then I will go to my childhood or school days, which are my best days of my life. I want to live again my childhood or school days with my childhood or school friends.

At that time, I played several sports including badminton, cricket, and football with my cousins or childhood friends. I want to time travel in my childhood days to remember my memorable childhood or school days. I want to meet again my school or childhood friends by  time travel to my memorable days.

I also enjoyed my birthday parties with my childhood friends during my childhood or school days. I want to attend again my birthday party with my parents with the help of time travel to my childhood days.

Thus, If I would time travel to any past days then I would go my my memorable childhood or school days.
