Do you use a calendar to help you organize your life？ By listing what you need to do on any special day，you can make sure to keep all for your appointments and not worry whether you've forgotten something．Calendars are also useful for reminding（提醒） people what day a certain holiday is on and what days you might have off from work． Besides， they are used for planning fun things like vacations and outings．

    A calendar is usually divided into twelve parts， and each one stands for a month with all the days laid out

in a grid﹣like（网格状的） form． A block of space usually is for one day， and there is enough space for you to write down what you need to do on that certain day． You probably use all different kinds of calendars． A calendar on your cell phone screen is easy to use， and so is a large paper calendar that hangs on your wall．
