When it comes to calculating dates in Excel, DATE is the most essential function to understand. As you probably know, Excel does not keep the year, month and day for a date, nor does it explicitly store weekday information in a cell. Instead, Microsoft Excel stores dates as serial numbers and this is the main source of confusion.

Not all Excel date functions can recognize dates entered as text values, therefore it's not recommended to supply dates directly in calculations. Instead, you should use the DATE function to get a serial number representing the date, the number that Excel understands and can operate on.
Excel interprets the year argument according to the date system set up on your computer. By default, Microsoft Excel for Windows uses the 1900 system where January 1, 1900 is represented by the serial number 1. For more details, please see Excel date format.
Tip. To avoid confusion, always supply four-digit years. For example, if you input "01" or "1" in the year argument, your DATE formula will return the year of 1901.MonthIf the month argument is greater than 12, Excel adds that number to the first month in the specified year. For example, DATE(2015, 15, 5) returns the serial number representing March 1, 2016 (January 5, 2015 plus 15 months).
If the month argument is less than 1 (zero or negative value), Excel subtracts the magnitude of that number of months, plus 1, from the first month in the specified year. For example, DATE(2015, -5, 1) returns the serial number representing July 1, 2014 (January 1, 2015 minus 6 months).
DayAs well as month, the day argument can be supplied as a positive and negative number, and Excel calculates its value based on the same principles as described above.
Instead of specifying the values representing the year, month and day directly in a formula, you can have some or all arguments driven by of other Excel date functions. For instance, combine the YEAR and TODAY to get a serial number for the first day of the current year.
As already mentioned, Microsoft Excel stores dates as serial numbers and operates on those numbers in formulas and calculations. That is why when you want to add or subtract some days to/from a given date, you need to convert that date to a serial number first by using the Excel DATE function. For example:
Assuming you are using a USB, Ethernet or Bluetooth device, when you open InstaCal, it shows you the device name, board number assigned, and in parenthesis the Identifier. When you double click on a listed device, among other parameters, it shows you the Factory Serial number, and Identifier. The factory serial number, as the name implies, is the serial number assigned at the factory during the manufacturing process and cannot be changed by any user. You can change the Identifier, either here in InstaCal, or via a library call to the Universal Library. For example, using the USB-1808: From the ULHELP, Identifier UL: cbGetConfig() ConfigItem = BIUSERDEVID maxConfigLen = up to 64 characters UL for .Net: GetUserDeviceId(), SetUserDeviceId()
You may use units and constants in your calculations. Once you perform your calculation, the result will be returned along with the most suitable unit. To do this, you must enter a value and an _ followed by a unit abbreviation. There are two ways to enter units and constants:
Convert is a free and easy to use unit conversion program that will convert the most popular units of distance, temperature, volume, time, speed, mass, power, density, pressure, energy, and many others, including the ability to create custom conversions!
In the diagram below, a command in Powershell lists some values regarding the above two USB devices. Clearly, what we have been calling the serial number does not conflate with what the identification in Powershell calls a serial number.
I tried the setup on a different computer we will call Computer 2. As if by magic, GSmartControl now showed me all of the correct information including serial number. Well now I have even bigger problems. Why would it work properly on Computer 2 but not Computer 1? What does the computer have to do with it?

this option outputs a self signed certificate instead of a certificate request. This is typically used to generate a test certificate or a self signed root CA. The extensions added to the certificate (if any) are specified in the configuration file. Unless specified using the set_serial option, a large random number will be used for the serial number.
serial number to use when outputting a self signed certificate. This may be specified as a decimal value or a hex value if preceded by 0x. It is possible to use negative serial numbers but this is not recommended.
Important: If the number of Compute nodes exceeds the number of license units, monitoring will be suspended until additional license units are applied. For example, if a SQL DW target with six compute nodes is being monitored with a six node license, and then two additional nodes are added to the SQL DW environment to accommodate increased activity, monitoring will stop until an updated license that includes additional license units is applied.
Sometimes it can be useful to identify computer hardware for inventory purposes using its serial number, which is often written on a small sticker affixed to the underside of the device. The serial number is also found in the BIOS, and can be retrieved using Windows Management Instrumentation (WMI).
The get-ciminstance PowerShell command was introduced in PowerShell 3.0. It allows administrators to run WMI queries on local or remote computers. To retrieve the BIOS serial number of the local computer, we need to access the Win32_BIOS WMI class. 2ff7e9595c
