For some of you, this is the first real-day anniversary of your birth that you will have had in four years. The question for some is “What’s the reason for a “leap year?” One answer is that Leap Years are needed to keep our modern day Gregorian Calendar in alignment with the Earth's revolutions around the sun. It takes the Earth approximately 365.242199 days—or 365 days, 5 hours, 48 minutes, and 46 seconds—to circle once around the Sun. This is called a tropical year. However, the Gregorian calendar has only 365 days in a year, so if the calendar didn't add a day on February 29 nearly every 4 years, the world would lose almost six hours off the calendar every year. After only 100 years, the calendar would be off by approximately 24 days. A similar February won't come again in the current generation’s because this February has four Sundays, four Mondays, four Tuesdays, four Wednesdays, four Thursdays, four Fridays, and four Saturdays. This only happens once every 823years. So, enjoy it!
