Project Calendar - Starting the Pseudocode

With a very simple obstacle taken down earlier this week, I have written the very first part of what is going to be a very complex Pseudocode.

This is, so far, a very simple Pseudocode and the following algorithms (offset, calculation, dynamic generation, etc.) are all going to be built around this Pseudocode unless I'm working out a logic problem/challenge.

The Pseudocode only handles the logic for generating a predefined month that starts on a Sunday. There are no offsets or not calculations. I did add, however, an IF statement to check wether the current Cell-day is past 31, if so there can be a different handling, like changing the background color of empty cells.

ALGORITHM
     A calendar-table generator. Currently with fixed month/year and no calculations.
     
CONSTANTS
     ...
     
VARIABLES
     rowIndex : INTEGER : Row FOR Loop index
     colIndex : INTEGER : Column FOR Loop index
     
     currentDay : INTEGER : Variable representing the current Day/Cell.
     
LOGIC
     LOOP FOR rowIndex FROM 0 to 6
          LOOP FOR colIndex FROM 1 TO 7
               currentDay ← colIndex + (rowIndex * 7)
     
               IF currentDay <= 31 THEN
                    WRITE currentDay //inside cell
               ELSE
                    WRITE "empty cell"
          END LOOP
     END LOOP
      
END
