I will share a simple trick for adding days or months to
dates and the result will be a custom date pattern. Check the script below…
If you want to add and subtract Months or Days on current
date:
$currentAddYears = [DateTime]::Now.AddYears(2)
$currentAddMonths = [DateTime]::Now.AddMonths(2)
$currentAddDays = [DateTime]::Now.AddDays(14)
$currentSubtractYears = [DateTime]::Now.AddYears(2)
$currentSubtractMonths = [DateTime]::Now.AddMonths(-2)
$currentSubtractDays = [DateTime]::Now.AddDays(-14)
Results
will be:
8/6/2014
2:23:00 PM #now
8/6/2016
2:23:00 PM #$currentAddYears
10/6/2014
2:23:00 PM #$currentAddMonths
8/20/2014
2:23:00 PM #$currentAddDays
8/6/2012
2:23:00 PM #$currentSubtractYears
6/6/2014
2:23:00 PM #$currentSubtractMonths
7/23/2014
2:23:00 PM #$currentSubtractDays
Now if
you want to change the results to custom format, you can use –format of Get-Date.
$format1 = Get-Date $currentAddMonths
-format "MMMM
yyyy"
$format2 = Get-Date $ currentAddDays
-format "MMMM
dd, yyyy"
Results
will be:
October
2014 #$format1
August
20, 2014 #$format2
