Frequently Asked Questions

Why does February 29th only happen every four years?
That's all about leap years! They add an extra day to February, making it 29 days long instead of 28. This adjustment keeps our calendar in sync with Earth's orbit around the Sun, which takes about 365.25 days. Without this extra day, we'd lose almost six hours every year.
What's so special about being born on February 29th?
People born on this day, known as "leaplings" or "leapers," have a unique birthday. They get to celebrate their actual birth date only once every four years. On non-leap years, some choose February 28th or March 1st for their celebration, but when leap year rolls around, it's extra special.
Are there any traditions or superstitions linked to February 29th?
Sure thing! One of the most famous traditions is that women propose to men on February 29th. This custom dates back to the 5th century in Ireland, with the legend of St. Bridget striking a deal with St. Patrick to allow women this right every four years, aiming to balance traditional roles in a fun way.
How many people in the world share a February 29th birthday?
It's estimated that about 1 in 1,461 people are born on February 29th, given the day's rarity. So, in a world of over 7 billion, that's around 5 million leaplings!
Can February 29th influence your zodiac sign?
Not really. Zodiac signs are determined by the sun's position in relation to constellations on your birth date. Since February 29th falls under Pisces, being born on this day doesn't change your zodiac sign from what it would be on February 28th or March 1st.
How do leap years affect annual events besides birthdays?
Annual events and fixed-date holidays remain unchanged, but for events tied to a specific week, like "the last Sunday in February," leap years can shift their occurrence. This might affect school calendars, sports schedules, and even some festivals, which have to adjust every four years.
Is there a way to calculate if a year will have a February 29th?
Yep, there's a simple rule. If the year can be evenly divided by 4, it's a leap year. However, if that year can also be divided by 100, it's not a leap year, unless it can be divided by 400. So, 2000 was a leap year, but 1900 wasn't. This keeps our calendar year closely matched with the astronomical year.
