To check the age of a domain, you can follow these steps:

1. Use WHOIS Lookup Tools:
   WHOIS lookup tools allow you to view information about a domain, including its registration date. There are many WHOIS lookup websites available where you can enter the domain name and retrieve its registration details. Some popular WHOIS lookup tools include ICANN WHOIS, WHOIS.net, and DomainTools.

2. Check the Creation Date in the Domain Registration Record:
   If you have access to the domain registration record, either through your domain registrar's dashboard or an email confirmation from when the domain was registered, you can find the creation date listed there. Look for a section that includes details such as creation date, expiration date, and registrar information.

3. Use Domain Age Checker Tools:
   There are online tools specifically designed to check the age of a domain. These tools typically retrieve information from WHOIS databases and present it in a user-friendly format. Simply enter the domain name into the tool, and it will display the registration date along with other domain details.

4. Check Historical WHOIS Records:
   Some advanced WHOIS lookup tools and domain research services offer access to historical WHOIS records. By viewing historical records, you can see changes in domain registration information over time, including the initial registration date.

5. Consider Other Factors:
   Keep in mind that the age of a domain is not necessarily an indicator of its credibility or quality. While older domains may have a more established online presence, newer domains can still be legitimate and reputable. Factors such as website content, backlink profile, and overall reputation are also important considerations.
