Must the first lunar month be silver moon?

If the first month is after beginning of spring, it is silver moon; if it is before beginning of spring, it belongs to the ugly twelfth month of last year, no matter whether it is a few days or dozens of days before beginning of spring. 201265438+1October 23rd is the first day of the first month, but the Spring Festival is the 13th day of the first month, and the first day is the December of the 20th11of the lunar calendar, which is a sad and ugly month. If it is before the first day of the first month in beginning of spring, it is the first month.
