My ID card shows that my birthday is February 28th, 2002. What is the exact date of 20 19?

It stands to reason that the birthday on February 28th, 2002 is the solar calendar, that is, February 28th of the solar calendar, the birthday of the lunar calendar, that is, the 17th of the first month, and the birthday of 20 19 is also February 28th, that is, the 24th of the first month. The key is whether you want the lunar calendar or the solar calendar. The current household registration book and ID card are all solar calendars, that is, solar calendars.
