A couple of days ago, one of my kids asked me “What day of the week will it be in 11 days from now?“. My response was “I’m not sure, but I can tell you how to figure out the answer for yourself“. Open up PowerShell, wrap Get-Date in parentheses, place a dot or period afterwards, followed by AddDays, then 11 in another set of parentheses, and finally another dot or period followed by DayOfWeek.
Want to know what the day of the week was 11 days ago instead? Simply use negative 11 (-11) which subtracts that number of days from the current datetime instead of adding it as shown in the previous example.
