Keterangan
Dimulai dengan .NET Framework 4.6, implementasi PersianCalendar kelas telah berubah dari algoritma pengamatan menjadi algoritma surya Hijriah. Akibatnya, IsLeapYear metode ini dapat mengembalikan nilai yang berbeda saat dijalankan pada .NET Framework 4.6 daripada saat dijalankan pada versi .NET Framework sebelumnya.
