How to Find out ESXi Installation Date?

In this blog I will walk you through to determine the installation date of an ESXi host.

To determine the installation date of an ESXi host, just follow the below steps.

  1. First Connect with your ESXi host through any SSH client – I used Putty
  2. Then execute this command,

      #echo -n “ESXi install date: ” ; date -d @$(printf “%d” 0x$(esxcli system uuid get | cut -d \- -f1 ))


  1. You will now see the installation date on the screen.

If you can’t remember this long command, no worries. We have a simple alternate way to do this.

  • Get the system UUID by executing the below command.

esxcli system uuid get


  • When this command is executed you will get the UUID of your Esxi host. From this copy the first 7 hexadecimal number. Like in my example its 52f35ae2
  • Now Convert this Hexadecimal number to decimal value, I prefer to use this online converter. (Hex to Decimal converter)


  • Now use Epoch Converter to Convert Decimal Number in to the Human Readable date.


You are done !!!
