The most important thing for a new company is to have a good name. The birthdates naming method is preferred by most private companies, so whose birthday should be used to name the company? The editor of Good Luck Constellation Network will popularize your knowledge about company naming.
The company name will use the date of birth of the legal person, and the company name must be consistent with the date of birth of the legal person. But the legal person mentioned here is not necessarily the legal person when the company was registered. A legal person is just a formality. Whoever has a great influence on the company will use its birthday. It might be the chairman's birthday, or it might be the manager's birthday. Bottom line: Whoever plays an important role in the company should use the company's date of birth, not necessarily the company's date of birth.
A company's name can generally only be given by one person, who plays a major role in the company. Other people's zodiac signs, such as your partner's, can be ignored. Of course, if two people have a similar impact on the company, their birth dates can be taken into account when naming the company.
