I'm assuming it's because that would the time if it were erev pesach today. In other words, the API just calculates the zmanim without checking if that zman applies that day? Can you please confirm or deny? (Sorry for the silly question, I'm a beginner in both Zmanim and Java, and made a simple program to output all (most) methods from ComplexZmanimCalender.)",

Once something is formally released, I have to support it long term, and I try to avoid rushing releases unless there is an important bug fix. Let me know if this answers your question.",
