February is a special month because it can lose or gain days during leap years.

Our calendar is based on how long it takes the Earth to go around the Sun. Usually, a year is about 365.25 days long.

So, every four years, we add one extra day to the calendar, making it 366 days for that year. This extra day goes into February, which normally has 28 days.

Key Points:

• Common Year: February has 28 days.
• Leap Year: In leap years, February has 29 days!

Why February?

1. History: Long ago, the calendar was based on moon phases, and February was the last month added.
2. Keeping Things Balanced: By adding an extra day, we help our calendar match up with the changing seasons.

For example, if your birthday is on February 29, you only get to celebrate it once every four years! How cool is that?
