I don’t understand this part “If the domain is transferred within 45 days after the expiration date, the Registry may not add an additional year.”. For example, today is July 18, 2024, and my domain name expires on August 20, 2024. If I transfer now, will I get another year? Or does it mean that now that I’ve successfully transferred the domain, I still have to renew it on August 20, 2024?
If you mean your domain is due to renew on that date and you renew it now, yes it will add a year. The message you seem to be worrying about is talking about renewing 45 days after the expiry, not before.
