Domain Age (DA) is the period of time that has passed since the domain was registered. This is one of the most important factors that affect the position of a given website in search results. A useful tool when you want to check the age of a domain is https://who.is/. All you have to do is enter the address of the domain and you will receive a lot of data about it, including: who owns it, which servers it is assigned to, and what interests us most - when it was first registered. The higher the DA, the "simpler" it should be to position the site. Another tool that can be used to determine the age of a domain is Domain Age Tool from Webconfs.
