Why should we say"Chinese New Year" and not "Lunar New Year"? Actually, all the Lunar New Year celebration happening right now should be called Chinese New Year celebration. The lunar calendar in fact is actually used by Muslims and the New Year for that calendar on 2025 is June 27th. So if you're celebrating on January 29th this year 2025, you should call it Chinese New Year, because it will be just inaccurate call it Lunar New Year. So Chinese New Year follows the unique Chinese Lunisolar Calendar. It's calculated by Purple Mountain Observatory in Nanjing, China, the history of the calendar can be dated back to about 4380 Year ago in Xia Dynasty, when Emperor Huang defeated Chio.
And just know that Chinese New Year is very inclusive, you're very welcome in one, the inclusivity notion and the name Chinese New Year, don't conflict at all, It's just a matter of being accurate. :)
