The Get-Date cmdlet gets a DateTime object that represents the current date or a date that you specify. Get-Date can format the date and time in several. You can use Get-Date to generate a date or time character string, and then send the string to other cmdlets or programs.

Get-Date uses the computer's culture settings to determine how the output is formatted. To view your computer's settings, use Get-Culture.

In this example, Get-Date displays the current system date and time. The output is in the long-date and long-time formats. This example shows how to use Get-Date to get either the date or time element. The parameter uses the arguments DateTimeor DateTime. Get-Date uses the DisplayHint parameter with the Date argument to get only the date. In this example, a. NET format specifier is used to customize the output's format. The output is a String object.

Get-Date uses the Format parameter to specify several format specifiers. For more information about. NET format specifiers, see Custom date and time format strings. In this example, several UFormat format specifiers are used to customize the output's format. 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.Use Windows PowerShell 3.

The script begins by loading two. NET Framework classes: System. Drawing and System. You then start a new instance of the. NET Framework class Windows. Form ; that provides a blank form or window to which you can start adding controls. This example assigns values to four properties of this class by using the Property property and hashtable.

Size : This is the size of the form, in pixels. Next, create and then add a calendar control in your form. In this example, the current day is not highlighted or circled. Users can select only one day on the calendar at one time. Next, create an OK button for your form.

Specify the size and behavior of the OK button. The button height is 23 pixels, while the button length is 75 pixels. The script uses predefined Windows Forms types to determine the button behaviors. Similarly, you create a Cancel button. The Cancel button is pixels from the top, but pixels from the left edge of the window.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I am writing a script in PowerShell and I need to know the dates between a range of dates. The script is to automate reporting. Let's say there is a bunch of logged data, but the data only gets collected on weekdays, no weekends and no holidays. I FTP and collect the last 15 generations logged.

With the script I open up the latest instance of the report in Excel. Once the workbook has opened up I read a cell which contains a date, that date will determine when the last time the report has been ran on.

Today's data however will not be accessible until tomorrow, so it is always 1 day behind. When I than have that date, I use Get-Date to get the current date. I need to know the dates between the current date and the date I read in from Excel. Afterwards I will need to see if any of the dates have fallen on a holiday, or if they have fell on the weekend.

Once I have those dates I can check to see if any of them were a holiday, and if they have fallen on a weekend. If they fell on a holiday I can subtract 1 day or 2 days if the last day in the report fell on a Friday I am still trying to figure out how I am going to do this. Here is another example that writes to a file. Learn more.

In this article I will demonstrate a few different ways that you can specify time and date ranges for message tracking log searches.

This is a useful technique because it can speed up your searches by minimizing the amount of log data that the search inspects. As an example of this speed difference, here is the result of Get-MessageTrackingLog for all logs on a single server. You can see that in a very large environment you will save yourself a lot of time by knowing how to narrow your message tracking log searches with time and date ranges.

There are two parameters for specifying time and date ranges when running the Get-MessageTrackingLog cmdlet.

Manipulating Date Ranges with Windows PowerShell

Both parameters accept values in the System. Quotes need to be used when specifying both a date and time.

Often you will find yourself in situations where you want to search the logs for a period of time without having to work out the exact start or end time for the search.

For example, you may wish to search only the last hour of logs because somebody has asked you to help troubleshoot a lost email that they only sent within the last hour. This is actually how I perform most of my own searches. On its own Get-Date returns a DateTime object and outputs a human-friendly version of it to your shell. I tend to use the AddHours and AddDays methods the most.

So now let's combine that with the Get-MessageTrackingLog -Start parameter to search the message tracking logs only for the last hour. As a general rule I use it on all searches just to save time.

In this scenario you might be tempted to specify the same value as both the start and end date, but this will return an error. That is more typing for the exact same result, so you may as well stick to the more efficient method of simply specifying the date on its own. As a follow on from the previous example it should by now be clear that you can search between any precise start and end times. For example, a search of all messages starting from noon on 17th September and ending 8 hours later.

This may seem a bit of a strange example, but the reason I'm using it is to demonstrate one little gotcha with DateTime values. But I can avoid this confusion and also save a little typing by capturing the start date in a variable first, that I can then re-use in my Get-MessageTrackingLog command, because once the DateTime object has been capture in a variable the regional settings become irrelevant and each cmdlet is able to interpret it correctly regardless.

This habit also gives you the advantage of a fixed point in time if you were running multiple searches moving through the logs hour by hour as I sometimes do.

As a final example remember that a good practice is to capture your message tracking log search results into a variable so that you can quickly and easily filter those results down further without needing to re-run your search.

For example, where in the previous command I collected all message tracking log entries for the 17th September, I can now filter that down to only those entries that were written between and He works as a consultant, writer, and trainer specializing in Office and Exchange Server.

I need to be able to add and subtract dates so that I can use the results in custom queries for various Windows event logs using Windows PowerShell.

Is doing this type of date manipulation easy or hard to do with Windows PowerShell? If it is not too difficult to do, could you whip up some examples of searching date ranges?

One of the things I used to hate about writing VBScript code was working with dates. It is not that it was difficult, but it did seem a bit arcane.

There must have been almost 20 different functions involved in date creation, parsing, and manipulation. Maybe not quite that many, but it seemed so. To make matters worse, I began to develop an aversion to parsing dates, and as a result I would do strange things to avoid parsing dates, which in turn made it more difficult due to lack of familiarity when I had to parse a date.

So the vicious circle continued to wobble out of control until one day I forced myself to spend a day writing nothing but date manipulation code. Luckily, date parsing and manipulation in Windows PowerShell is much easier.

NET Framework object. Why, you may ask, do I refer to the system. NET Framework object when just a minute ago I was talking about dates? You can use the Get-Member cmdlet to see what type of object you are working with. The Get-Date cmdlet returns the current date and time.

When the current date and time are piped to the Get-Member cmdlet, the members of a System. NET Framework class are displayed. This is shown here:. DateTime Add System.

TimeSpan Subtract System. The members, methods, and properties of the System. NET Framework class that are displayed are instance methods and properties. This means that they work on an instance of the class.For example, I have occasionally written scripts that pull Windows event logs from a particular date or scripts that archive aging data based on the date when a file was created.

Those are just a couple of examples of how the date may need to be referenced within a PowerShell script. In this article, I want to show you a few tricks for working with dates in PowerShell.

It is simple to make PowerShell display the current date. To do so, just enter the Get-Date cmdlet. If you need to display the date in a certain way, then PowerShell offers a number of different options for doing so. The simplest method is to use a display hint. The image below shows how the basic Get-Date cmdlet works, and a few examples of using the DisplayHint parameter.

If you need a bit more control over the output, you can use the Format parameter or the UFormat parameter. The Format parameter is mostly used when you need to put the date into a certain format for the purpose of making a comparison. The UFormat parameter is used more for display purposes. It allows you to arrange the various elements that make up the date and time in a way of your choosing. All you have to do is to append various formatting characters to the UFormat parameter.

The parameters that you can use include:. For example, -5 is Eastern Time in the United States. There are two things that are worth paying attention to in the image above.

First, you will notice that everything following the UFormat parameter is enclosed in quotation marks. This is because I am not just specifying formatting characters, I can also use text. In the figure, I used a mixture of text and formatting characters. The other thing to notice is that even though I live on the East Coast of the United States, which normally has a time zone offset of -5, the output in the figure above shows the offset as This is because it is daylight saving time.

We can actually. As you can see in the image below, PowerShell shows a value of True, indicating that it is indeed daylight savings time. If you really want to make things interesting, though, you can specify a date to find out what day of the year that date falls on.

The date that you specify can be past or future. Here is an example:.

Get-Date -Year -Month 8 -Daye You can see a couple of examples in the image below. As I said earlier, it is possible to use PowerShell to make date comparisons. Although you can use the -Format parameter to put the date into a specific format prior to comparing it to another value, doing so is not always necessary.

For example, comparing file write dates does not require the use of any special formatting. In a situation like this, the first thing that we have to do is to map our target date to a variable. It will then be possible to make comparisons between the two.
