Leap years in the Japanese calendar correspond to the same leap years in the Gregorian calendar. A leap year in the Gregorian calendar is defined as a Gregorian year that is evenly divisible by four, except if it is divisible by 100. However, Gregorian years that are divisible by 400 are leap years. A common year has 365 days and a leap year has 366 days.
The following code example calls the IsLeapYear method for five years in each of the eras.
using System; using System.Globalization; public class Example { public static void Demo(System.Windows.Controls.TextBlock outputBlock) { // Creates and initializes a JapaneseCalendar. JapaneseCalendar myCal = new JapaneseCalendar(); // Displays the header. outputBlock.Text += "YEAR\t"; for (int y = 1; y <= 5; y++) outputBlock.Text += String.Format("\t{0}", y); outputBlock.Text += "\n"; // Checks five years in the current era. outputBlock.Text += "CurrentEra:"; for (int y = 1; y <= 5; y++) outputBlock.Text += String.Format("\t{0}", myCal.IsLeapYear(y, JapaneseCalendar.CurrentEra)); outputBlock.Text += "\n"; // Checks five years in each of the eras. for (int i = 0; i < myCal.Eras.Length; i++) { outputBlock.Text += String.Format("Era {0}:\t", myCal.Eras[i]); for (int y = 1; y <= 5; y++) outputBlock.Text += String.Format("\t{0}", myCal.IsLeapYear(y, myCal.Eras[i])); outputBlock.Text += "\n"; } } } /* This code produces the following output.
