Let's break this code down step-by-step:

var daysInMonth = DateTime.DaysInMonth(now.Year, now.Month);

1. This line calculates the number of days in the month for the current year (now.Year) and the current month (now.Month).
   • DateTime.DaysInMonth(year, month) is a built-in .NET function that returns the total number of days in the specified month and year.
   • The result is stored in the variable daysInMonth.

var lastDay = new DateTime(now.Year, now.Month, daysInMonth);

2. This creates a DateTime object representing the last day of the current month.
   • It uses the daysInMonth variable as the day component, which corresponds to the maximum valid day in the current month and year.
   • The result is stored in the variable lastDay.

var latFriday = new DateTime(mow.year, now.month, lastFriday);

3. This line contains a syntax error and/or typos:
   • latFriday may have intended to be lastFriday.
   • mow.year should likely be now.Year, and mow.month should be now.Month.
   • lastFriday is used incorrectly as a value when it hasn't been previously defined.

If corrected, this part of the code might be attempting to calculate or define the last Friday of the month, but it is currently nonsensical due to the existing typos. The code will throw a compile-time error unless it's fixed.
