Leap year: How does it work? Why February 29?
Subject: Geography
Section: Msc
Context:
- This year, February will be a day longer than usual as 2024 is a leap year.
About Leap Year:
- Leap years are characterized by the insertion of an extra day i.e. February 29 ,every four years is crucial for maintaining the precision of our calendar.
- The periodic adjustment aligns our societal timekeeping with the Earth’s orbital cycle around the sun, highlighting the intricate balance between human conventions and natural phenomena.
- 2024 is a leap year , a calendar oddity that adds one extra day to the otherwise 365 days that form a year.
Why Do We Need Them?
- Our calendar year consists of 365 days, but the Earth’s journey around the sun actually takes about 365.24 days.
- That difference might seem small, but over time, it adds up.
- Without leap years, our calendar would gradually fall out of sync with the seasons.
- Imagine if summer started in December instead of June.
- Leap years ensure that doesn’t happen by adding an extra day i.e. February 29,every four years.
The Mechanics of Leap Years: How Do They Work?
- Leap years operate on a simple principle: adding one extra day every four years helps to balance out the discrepancy between our calendar and the solar year.
- By adding that extra day, we overshoot a bit, accumulating about 44 extra minutes every four years.
- To counteract this, we skip leap years every century, except for those divisible by 400, like the year 2000.
Why February 29?
- February was the natural pick , for the addition of an extra day.
- It’s the shortest month of the year, making it the perfect candidate for an extra day.
- This addition helps to keep everything in sync without throwing off the balance too much.
