This code calculates the last day of the current month...

This code calculates the last day of the current month and assigns it to the variable lastDay. Here’s a detailed explanation:

1. DateTime: This is an object used to work with date and time values (e.g., in .NET languages like C#).

2. now: This variable is expected to hold the current date and time (e.g., from DateTime.Now).

3. now.Year: Extracts the current year from the now variable.

4. now.Month: Extracts the current month from the now variable.

5. daysInMonth: Presumably, this variable holds the total number of days in the current month. This value could be obtained using a method like DateTime.DaysInMonth(now.Year, now.Month).

6. new DateTime(now.Year, now.Month, daysInMonth): Creates a new DateTime object representing the date that corresponds to the last day of the current month (using the year, month, and the last day as the daysInMonth).

Overall:

The code creates a DateTime object for the last day of the current month based on the current date stored in now. The result is stored in the lastDay variable.
