Get-Date uses the UFormat parameter to specify several format specifiers. For a list of valid UFormat format specifiers, see the Notes section. The Gregorian calendar has days, except for leap years that have days. For example, December 31, is day Get-Date uses three parameters to specify the date: Year , Month , and Day.

The command is wrapped with parentheses so that the result is evaluated by the DayofYear property. In this example, the current time is converted to UTC time. The UTC offset for the system's locale is used to convert the time. A table in the Notes section lists the valid UFormat format specifiers. Get-Date uses the UFormat parameter with format specifiers to display the current system date and time. In this example, a format specifier creates a timestamp String object for a directory name.

The timestamp includes the date, time, and UTC offset. Get-Date uses the Format parameter with the format specifier of lowercase o to create a timestamp String object. The object is sent down the pipeline to ForEach-Object.

The timestamp string is delimited by colons that are replaced by periods. New-Item uses the Path parameter to specify the location for a new directory.

Another way to generate the file name based on Get-Date would be to use the ToString method and specify the exact output you want, like this:. Another point worth making is that Windows tries to display dates in a culture-aware way. Get-Date does a fairly good job in most cases of converting a date string into the date you wanted. But if you want a specific result, using ToString and a date format string is possibly better — and fewer lines of code.

What could still be optimized: Other processes might get confused if using the date format in the short period while it is modified. So parsing the output according to the existing format string could be 'safer' - but will be more complicated. I used date. PowerShell Try the code below.

It will create the file or folder varible with the date as ddmmyyhhmm in 24hour time. Given a known locality, for reference in functional form. I know that there are numerous ways mentioned already. But here is my way to break it down to understand how it is done. Hopefully, it is helpful for someone who like step by step method. My solution is for the UK though.
