Work Marked Late -Either VBA Or Worsheet Function

I have a very large spreadsheet with the following columns: WO# (number field); Start date (date format MM/DD/YYYY); Frequency (text); and craft (number). I am trying to have code that checks the frequency and if is "Monthly" or "Weekly" it just goes on to the next row; if it is "Annual", it adds 163 to the start date (start date needs to changed to a numeric field); if it is "Semi-annual", it adds 82 to the start date; if it is "Quarterly", it adds 45 to the start date; and so on, there about 20m different frequencies. After it adds the above value to the start date, I need to check if that number is less than today's date (the day I run the code). If it is, it needs to flagged as "LATE" and the whole row of info copied to another worksheet with LATE as the title and all the column headings and info copied to the worksheet. I hope this makes sense to someone because I am a beginner in Excel and even less informed when it comes to VBA. Any help would be greatly appreciated.

The way the process must work is that I need to check the frequency and if it is "Weekly" or "Monthly" , it is ignored and goes on to the next row. All other frequencies are cut in half, i.e., "Annual" is 183 days, "Semi-annual is 92 days", "Quarterly" is 45 days, "2-Year" is 365 days, and so on. This number needs to added to the scheduled start date (now formatted as a number, not a date, and checked to see if it is smaller than today's date (also a number). If it is, it is reported on the second worksheet (titled Late).
