Powershell's Get-date: How to get Yesterday at 22:00 in a variable?

Question

For a check i need yesterday\'s date at 10:00pm in a variable.

I get yesterdays Date and current Time with

$a = (get-date).AddDays(-1)

Answer 1

Format in other syntax is possible in this way

[DateTime]::Today.AddDays(-1).ToString("yyyyMMdd")

Answer 2

(Get-Date (Get-Date -Format d)).AddHours(-2)

Answer 3

When I was to get yesterday with just the date in the format Year/Month/Day I use:

$Variable = Get-Date((get-date ).AddDays(-1))  -Format "yyyy-MM-dd"

Answer 4

Yet another way to do this:

(Get-Date).AddDays(-1).Date.AddHours(22)

Answer 5

I see this topic, but in my case I was looking for a way to improve the format. Using UFormat and adding -1 day

(get-date (get-date).addDays(-1) -UFormat "%Y%m%d-%H%M")

Answer 6

Use DateTime.Today as opposed to DateTime.Now (which is what Get-Date returns) because Today is just the date with 00:00 as the time, and now is the moment in time down to the millisecond. (from masenkablast)
