Replying to @Midnight yes but actual solar time of birth may differ to your birth certificate birth time #chineseastrology #bazi #astrologychart #birthchart #natalchart

Yes, you can see as it says here, you put it in using the Gregorian calendar, so your actual date and time of birth. Your Chinese astrology chart is not calculated based on the lunar calendar, it's the Chinese solar calendar, so using Joey App's website will automatically convert your Gregorian birthday into the Bards of Calendar that we use. You can use your normal birth time, but this time might not actually be accurate, because in Bards, we want to work with your accurate solar time, which sometimes shifts a little bit based on how far away your birth location was from your time zone line. It's a little bit more confusing and it's actually a manual calculation that I have to do for every chart that I pull.
