Why does my birthday change?
Your birthday changes because a regular year is 365 days long, which is 52 weeks plus one day, and this extra day causes your birthday to fall on a different day of the week each year, unless there’s a leap year in between, which would then make it fall two days later. The birth date and day of the week may not align every year due to the Earth’s orbit around the sun, resulting in an extra day added to the calendar almost every four years, known as a leap year, to keep our calendar in sync with the Earth’s orbit.
Understanding Birthday Changes
The reason behind the change in birthday falls is due to the calendar system we use, which is based on the Earth’s rotation and orbit around the sun. The calendar year is approximately 365.24 days long, so to account for this extra fraction of a day, an extra day is added to the calendar every four years, making it a 366-day year, known as a leap year.
Leap Years and Their Impact
Leap years play a significant role in determining the day of the week your birthday falls on. If your birthday is on or after February 29th, your birthday will fall on the same day of the week the following year. However, if your birthday is before February 29th, your birthday will fall a day later in the week the following year, unless it’s a leap year, in which case it will fall two days later.
