Friendly reminder: According to relevant regulations, the Gregorian calendar date must be used for household registration management in China. However, this regulation is only implemented in municipalities directly under the central government and provincial capitals, and grass-roots staff in some areas often use the lunar calendar date according to residents' declarations. This kind of situation often happens, and it has been basically eliminated at present.
