How can I use Windows PowerShell to see the number of days until the end of the year?
Use the New-TimeSpan cmdlet. Use Get-Date for the start and the day you wish for the end. The following shows this technique by using a U.S. English cultural setting.
New-TimeSpan -Start (get-date) -End 12/31/2012
Great Answer !
A simple solution, but ... 31/12/2012 works better.
New-TimeSpan -Start (get-date) -End (Get-Date -Day 31 -Month 12 -Year (Get-Date).Year) | select -ExpandProperty TotalDays
Works every year, for every system locale (sorry, I couldn't leave it like that).
Any tips on an internationalazed version of this question? But much more helpful would be a answer that works for any year. Is this possible?
Thanks siodmy, great one-lineable answer. Sorry I read these on mobile.
If you use ISO notation it is also independent of regional settings:
New-TimeSpan -Start (Get-Date) -End 2012/12/31
Using 1/1/2013 would fix us\uk date format and fix the day early since the time defaults to 0:00:00am not 11:59:59pm
@Thomas Ertl thanks :-)
@siodmy hmmmm I did not think about that one. Great answer!
@Conrad braam I have a whole series of Hey Scripting Guys blog posts where I talk about detecting and selecting specific locale settings. Here are a few articles to get you started: social.technet.microsoft.com/.../en-US
@Jaap Brasser, yes that is a good point
@Michael Menzies cool ... I did not know that.
