How to declare an array using get-date?

I'd like to declare an array of dates in powershell, it's not a continuous range, so I cant do anything clever with loops.

I've tried using the array notation with a call to get-date, as below, but this returns an error

$logDateList = 
@(Get-Date -Year 2017 -Month 08 -Day 22 -Hour 13
,Get-Date -Year 2017 -Month 08 -Day 20 -Hour 22)

How can I declare an array of dates in powershell?

You can cast a string to a datetime like this:

[datetime]'2017-08-22 13:00'

and make your array

$logDateList = [datetime]'2017-08-22 13:00', [datetime]'2017-08-20 22:00'

and if you're doing that, make it one array of string dates, and cast to an array of datetime

[datetime[]] $logDateList = @(
    '2017-08-22 13:00', 
    '2017-08-20 22:00'
)

I put them in ISO standard yyyy-MM-dd hh:mm order to avoid US/UK parsing confusion.

I'd argue that you should still use a loop for this to save yourself some code duplication:

$logDateList = '20 Aug 2017 22:00','22 Aug 2017 22:13' | ForEach-Object { Get-Date $_ }

Example using text for months in the interests of avoiding regional issues but you could format your dates in whatever way you like that works for you.

Just wrap each Get-Date in brackets:

$logDateList = @((Get-Date -Year 2017 -Month 08 -Day 22 -Hour 13),(Get-Date -Year 2017 -Month 08 -Day 20 -Hour 22))
