ClearBaZi - Free BaZi and zodiac calculators that flag tricky births

I built ClearBaZi after noticing that free BaZi sites often give the same person different charts. The cause is almost always an input convention: clock time vs true solar time, old daylight saving rules, or whether the year starts at Chinese New Year or the Start of Spring. ClearBaZi handles these explicitly and tells you when your birth is close enough to a boundary that the answer depends on the convention. The method and cross-check results are public on the Accuracy page. Feedback very welcome, especially from people born in late January or early February.
