The perception of time is shortened when one is "having fun".

Fun is the enjoyment of pleasure and, according to Johan Huizinga, "an absolutely primary category of life, familiar to everybody at a glance right down to the animal level."

Here is a picture of some kids having fun in the Bellingen river in the very late afternoon.  The time was well after 6.00pm in the evening.

 Fun may often have little to no logical basis, and opinions on whether or not an activity is fun may differ. I for instance find doing housework enjoyable.  I absolutely love the punishing work of Garlic and find this very enjoyable and it borders on being fun.  Why?  Because I laugh a lot and that is good for you and so that is fun to me.

One might be close to the truth saying that we can have more fun simply because we use the Daylight Saving System of time.  We get more daylight for our hours.  It always bamboozles me, I get it mixed up constantly and I personally was not in favor of it being introduced fun or no fun.  It upsets kids routines and their very important body clocks.  They ought ban the practice I feel.
