I’m sorry for the confusion, but as of the current information available publicly, there doesn’t appear to be a top-level domain (TLD) named .NOWRUZ. Top-level domains are the highest level of domain names in the root zone of the Domain Name System (DNS) of the Internet. Generally, these could be generic TLDs (gTLDs) like .com, .org, and .net, or country code TLDs (ccTLDs) like .us (United States), .uk (United Kingdom), or .au (Australia), among many others.
The Internet Assigned Numbers Authority (IANA), part of the Internet Corporation for Assigned Names and Numbers (ICANN), is responsible for the global coordination of the DNS Root, IP addressing, and other Internet protocol resources. To introduce a new TLD, a comprehensive application process must be followed through ICANN’s New gTLD (generic top-level domain) Program.
By checking the IANA’s Root Zone Database, which contains the authoritative listing of all TLDs, it can be seen that .NOWRUZ doesn’t exist. Nor is it found in ICANN’s list of applied-for new TLDs where internet users can see all of the new generic top-level domain names that have been applied for.
Nowruz refers to the Iranian New Year, also known as the Persian New Year, which is celebrated worldwide by various ethno-linguistic groups. It’s been celebrated for over 3,000 years in the Balkans, the Black Sea Basin, the Caucasus, Central Asia, and the Middle East. It happens on the vernal equinox, marking the beginning of spring on the Northern Hemisphere. However, no TLD under the name .NOWRUZ has been established yet.
It’s worth noting that the available TLDs are ever-evolving and changing based on the needs and innovations of internet users and organizations worldwide. The process of introducing a new gTLD is a long and thorough process overseen by ICANN.
Sources used to construct this answer include the IANA’s Root Zone Database (https://data.iana.org/TLD/tlds-alpha-by-domain.txt), as well as ICANN’s official page on the New gTLD Generic Top-Level Domains Program (https://newgtlds.icann.org/en/program-status/application-results).
With internet continuing to evolve, there may be possibilities in the future for culturally-significant terms such as Nowruz to be included as TLDs, further promoting their recognition and understanding worldwide in the digital space. At the moment, however, no such TLD exists.
