Domain Age Calculator Complete Guide 2025: Check Domain Registration Date & Age
Domain age is a crucial factor in SEO and domain valuation. Understanding when a domain was registered can help you make informed decisions about domain purchases, SEO strategies, and website development. This comprehensive guide will teach you everything about domain age calculation and how to use our free domain age calculator.
What is Domain Age?
Domain age refers to the time elapsed since a domain was first registered. It's calculated as the difference between the current date and the domain's registration date. Domain age is publicly available information that can be retrieved through WHOIS lookup.
Why Domain Age Matters
- SEO Impact: Older domains often have better search engine rankings
- Domain Authority: Established domains typically have higher authority scores
- Trust Factor: Older domains are generally perceived as more trustworthy
- Backlink History: Aged domains may have accumulated valuable backlinks
- Market Value: Older domains often command higher prices

Domain Age Calculation Formula
The basic formula for calculating domain age is:
Domain Age = Current Date - Registration Date
Example Calculation
