Panchaka (Panchak) is the span when the Moon transits the last five nakshatras: Dhanishta, Shatabhisha, Purva Bhadrapada, Uttara Bhadrapada, and Revati. Many Rajasthan households avoid starting a house, a wood-related task, or certain funeral rites in this window. It is not Rahu kalam. It can last more than one civil day.
On the day page we mark Panchaka from the nakshatra at sunrise — the same nakshatra the stored panchang already shows. If that name is one of the five, the day is flagged. When the Moon leaves Revati, the flag clears even if the newspaper still says “panchak chal raha hai” from a different city.
Vivah and griha pravesh finders list Panchaka days but do not hide them. Families who observe the restriction can skip those rows. Families who only avoid specific works can still use an Amrit watch outside Rahu kalam.
This is a traditional caution, not a medical or legal rule. Confirm with the pandit who will sit the karma if the work is a samskara.
