What can I do with this system value?

You can specify the leap year adjustment for your system. By setting this system value requiredly, your system's date will be correct from year to year.

This system value adjusts the system calendar for the leap year in different calendar systems. If your calendar year agrees with the Gregorian calendar system, select Use Gregorian leap year adjustment (0). If your calendar year differs from the Gregorian, adjust the system calendar to account for the leap year of the calendar year you are using. To make the adjustment, divide the leap year in your calendar system by 4; then set Leap year adjustment to the value of the remainder.

For example: The Gregorian calendar year of 1984 was the year 2527 in the Thai Buddhist calendar. Because 2527 was a leap year, you divide 2527 by 4; this leaves a remainder of 3. Therefore, to adjust the system calendar for the Thai Buddhist calendar, specify 3 for Leap year adjustment.
