# Instructions | ||
|
||
Given a year, report if it is a leap year. | ||
|
||
The tricky thing here is that a leap year in the Gregorian calendar occurs: | ||
|
||
```text | ||
on every year that is evenly divisible by 4 | ||
except every year that is evenly divisible by 100 | ||
unless the year is also evenly divisible by 400 | ||
``` | ||
|
||
For example, 1997 is not a leap year, but 1996 is. 1900 is not a leap | ||
year, but 2000 is. | ||
|
||
## Notes | ||
|
||
Though our exercise adopts some very simple rules, there is more to | ||
learn! | ||
|
||
For a delightful, four minute explanation of the whole leap year | ||
phenomenon, go watch [this youtube video][video]. | ||

# Introduction | ||
|
||
A leap year (in the Gregorian calendar) occurs: | ||
|
||
- In every year that is evenly divisible by 4. | ||
- Unless the year is evenly divisible by 100, in which case it's only a leap year if the year is also evenly divisible by 400. | ||
|
||
Some examples: | ||
|
||
- 1997 was not a leap year as it's not divisible by 4. | ||
- 1900 was not a leap year as it's not divisible by 400. | ||
- 2000 was a leap year! | ||
