The terms 'leap day' or 'leap month' are often mentioned, but few know the specific significance of these terms. The following article will provide readers with a general overview and explore interesting facts related to leap days and leap months.
Why do we have leap days?
According to scientists, the Earth's orbit around the Sun is 365 days and 6 hours. So every year in the Gregorian calendar has 365 days plus an extra 6 hours, resulting in 24 extra hours every 4 years, which equals one day. Therefore, every 4 years, there is a year with 366 days, and this day is added to February (February 29th). Hence, February 29th is called a leap day.
What's special about leap day, February 29th?
Those born on February 29th are very special because their birthdays occur only once every 4 years. This difference makes babies born on that day more special in the eyes of everyone around them.
In addition, in Western countries, this is also a day for women to propose to men. According to legend, in early 5th-century Ireland, women had to wait for men to express their love without actively seeking it themselves. This made Saint Kildare sad, lamenting to Saint Patrick.
Since then, Saint Patrick has allowed women to propose to men on leap day, February 29th. Later on, this tradition has been maintained and developed into 'Women's Rights Day' on February 29th.
In Western countries, leap day sees many festivals and even cities dedicated to those born on February 29th. There, they celebrate with grand feasts, indulge in games, and birthdays are celebrated extravagantly.
