Have you ever wondered why we have leap years and why February gets an extra day every four years? Leap years have been around for centuries, yet few people truly understand their significance. In this article, we’ll explore why leap years exist, some fascinating facts about them, and – because we love languages – how this calendar phenomenon has influenced the way we speak.

Why Do We Need Leap Years?

Leap years exist for one simple reason: The Earth doesn’t orbit the sun in exactly 365 days – it takes about 365 days and 6 hours. If we ignored these extra hours, the seasons would gradually shift, and in a few centuries, we’d be celebrating Christmas in the middle of summer. To prevent this, we add an extra day every four years – February 29, also known as Leap Day.

However, the system isn’t as simple as it sounds. You may have heard that leap years are those divisible by 4, but there’s an exception! Years divisible by 100 are not leap years unless they are also divisible by 400. For example, the year 1900 was not a leap year, but the year 2000 was.

What Does Leap Year Have to Do with Language?

You might be wondering: What’s the connection between leap years and language? Surprisingly, quite a lot! Many languages, including English, have unique phrases and linguistic quirks related to leap years and February.

The Meaning of "Leap" in Language

The word leap year comes from Latin: annus bissextilis, meaning "double sixth day." In ancient Rome, an extra day was added after February 24 and was called bissextus, meaning "twice the sixth."

Interestingly, the word leap itself appears in many idioms that align with the idea of something unexpected or out of the ordinary:

• Take a leap of faith → Making a bold decision, much like February suddenly extending itself.

• Leap at an opportunity → Grabbing something rare – like an extra day in the calendar!

Idioms and Superstitions Around Leap Years

Leap years are often associated with myths and traditions:

• In English, leap of faith describes taking a risk without knowing the outcome – similar to the unpredictable nature of leap years.

• In Italian, leap years are considered unlucky, as shown in the saying Anno bisestile, anno funesto ("Leap year, doom year").

• In Russian, it’s believed that getting married or buying a house in a leap year brings bad luck.

When Do Leap Day Babies Celebrate Their Birthdays?

People born on February 29, known as leaplings or leapers, have a unique birthday. Since their actual birth date only appears every four years, they either celebrate on 28 February 28 or 1 March in non-leap years.

In some cultures, there’s even a joke that leaplings age four times slower because they only get a "real" birthday once every four years!
