f52 : The display or output year is calculated using the following formula. Display/output year = (Christian era) + (f52)

Example 1: Christian era = (20)05, f52 10 then display/output year = (20)15

Example 2: Christian era = (20)05, f52 99 then display/output year = (20)04 Keep the internal year in Christian era format because the leap year correction is made based on the Christian era.

f53 and f54 : 2 characters can be added preceding the internal year to the output of the year. Additional characters are set at f54. A 4 digit year can not be displayed.

f53 0 Add no character, output year is 2 characters.

f53 1 Add 2 digit numeric characters. The 2 digits number does not increment automatically if the internal year changes from 99 to 00.

Example: Setting f54 20, internal year (after f52 calculate) = 05, output year = 2005
