What a muhurat calculation needs
A clock interval, a traditional rule and a personal recommendation are three different things.
Begin with a defined question
A daily time segment and a ceremony-specific muhurat are different products. A general daylight partition can be computed from local sunrise and sunset using an explicit weekday mapping. A marriage or house-entry selection may require additional calendar and personal rules. Calling both “good time” conceals those differences.
Location and day boundaries
Day and night do not have a constant duration throughout the year. Nighttime partitions may need the next morning’s sunrise. A valid implementation must handle the date, city, timezone and intervals crossing midnight. A fixed daily clock table cannot represent all those conditions.
Name the tradition
Rahu Kalam, Hora, Choghadiya and Abhijit each need their own definition and test cases. They should not be interchangeable coloured blocks. Regional practices may differ, and an owner-approved method must state which rules are supported. This preview leaves unapproved recommendation windows unavailable.
Use an interval with context
When a reviewed interval is eventually published, read its city, date, timezone, tradition and intended activity. A traditional timing recommendation is not a guarantee of the result of a decision. Practical preparation, consent and the real constraints of a ceremony remain relevant.
