February 29 is a date that usually occurs every four years, and is called leap day. This day is added to the calendar in leap years as a corrective measure, because the earth does not orbit around the sun in precisely 365 days.
Use this extra 24 hours to think about just how much happens every single day, and different ways to quantify a day.
For example, how money does an agricultural engineer earn on a daily basis? How much does the average American spend on food each day? How much milk is produced by your nearest dairy farm in one day?
Questions like these can really help give you a better perspective on what a day really means!
