For convenience and accuracy in the future, you should remember the solar calendar, that is, 199 1. 1.25.

On the one hand, some people sometimes don't even know the month, let alone the date. On the other hand, if you fill in the form as1990.10.13, others will think it is the Gregorian calendar, so you have to explain it frequently. Third, isn't it smaller to fill in the solar calendar? Maybe when you grow up, just because you are one year younger will bring you benefits (but not much).

Do the math and see what it is.

Personal fortune telling, people use gossip to tell fortune, and the lunar calendar is used to calculate marriage. The Gregorian calendar is used to calculate constellations and horoscope, because the calculation time of horoscope is only when the solar terms are on the sun, not the moon time. Now all official horoscopes are based on the Gregorian calendar. Modern young people mostly tell fortune online, and most of them know that they use the Gregorian calendar. Note: Eight-character fortune-telling also needs to know the birth time and approximate location.

Now use gossip to calculate other things or use the lunar calendar.
