FAQ
Why does each day show two date lines?
Each day cell shows the Gregorian day number and a lunar label. Solar terms or festivals are shown first when they make the date easier to recognize.
Can traditional day notes be treated as formal advice?
No. Day notes are traditional reference text for display only and are not life, legal, medical, financial, or other professional advice.
