Hi everyone!
3rd graders have to study a new poem for next Monday: "30 days".
This rhyme goes back to the 15th century!
Someone who learns that poem can also learn what a leap year is.
A leap year happens every four years and has 366 days and it has an extra day in it.
The extra day is added at the end of the shortest month, February!
Last leap year was 2012, so the next will be in 2016.
