We use time to order events in the past, present and future. If you want to measure time, you can use a watch, clock, hourglass or even a sundial . There are 60 seconds in a minute, 60 minutes in an hour and 24 hours in a day. Normal years have 365 days but a leap year has 366. Different parts of the world are located in different time zones . Here are a few questions to get your brain buzzing : Does time have a direction ? Did it begin with the Big Bang ? Is time travel possible ?
