WebIn speaking, people generally call the date in the Gregorian calendar month "No. dd", for example, the Spring Festival of year 2017 is No. 28 of Month 1 (simplified Chinese: 1月28号; traditional Chinese: 1月28號) On the other hand, people never call dates on the Chinese calendar as "No. dd"., which avoids any possible ambiguity.
