The day before yesterday I was 25 The next year l will be 28

Can you solve this tricky riddle?

The day before yesterday I was 25 The next year

The day before yesterday I was 25. The next year l will be 28.

This is true only one day in a year. What day is my birthday?

Your birthday is on 31st December.

The day before your birthday you are 25 years old and on your birthday you will become 26 years old.

And on this year’s 31st December you turned one year older. That is 27 years old. So you will become 28 years old in next year.

In other words the day before yesterday you were 25. Yesterday you turned 26, this year you will turn 27 and next year you will turn 28.
