The month of the year (QMONTH) is used to indicate the month of the year on the server.
This value must be a number from 1 (January) through 12 (December) if your system date format uses the Gregorian calendar. This value cannot be displayed or changed if your server date format uses the Julian format (year, day of year).
You can change the month to reflect the current month in your country or location. If you change QMONTH, you also change the value for QDATE. A change to this value takes place immediately.
