input_Lilian_date (input): A 32-bit binary integer representing the Lilian date, which is the number of days since 14 October 1582. For example, 16 May 1988 is day number 148 138. The valid range is 1 to 3 074 324 (31 December 9999).
output_day_no (output): A 32-bit binary integer representing the day of week of the input_Lilian_date. For the day of week, 1 indicates Sunday, 2 indicates Monday, ..., 7 indicates Saturday. If input_Lilian_date is not valid, output_day_no is set to 0 and CEEDYWK ends with a nonzero feedback code.
