isLeapYear property

bool isLeapYear

Returns true if this is in a leap year.

In the Gregorian calendar, three criteria must be taken into account to identify leap years:

• the year must be evenly divisible by 4;
• if the year can also be evenly divided by 100, it is not a leap year;
• unless the year is also evenly divisible by 400. Then it is a leap year.

Implementation

bool get isLeapYear => _isLeapYear(year);
