Because they are useful for predicting the future.
Primitive people in the tropics have no real need for calendars; the weather doesn't change all that much from day to day. In the temperate zones, it's important to know when to plant, and when to harvest, and when to expect recurrent events.
One of the earliest calendars we know of was used to keep track of the seasons along the Nile River in Egypt; if you knew approximately when the Nile floods would occur each year (and they are fairly predictable!) then you knew more or less when to move to higher ground and when it might be safe to return.

A Leap Minute is a minute that is added or removed according to what's needed to keep our clocks and calendars in synch with the movement of our planet and the sun. The movement of the Earth around the Sun, and around its own axis, doesn't match up exactly to our clocks and calendars. To prevent the error from growing year after year, Leap days, leap hours, leap minutes, even leap seconds, are regularly added to keep everything in synch.
