In the 24th part of the Mahabharata series, Karna tells Krishna the 3rd nimitta (omen). He mentions that Gara Karana, one of the five angas of Panchanga, is afflicting Chitra Nakshatra. This implies a shift in tithi (lunar day), suggesting Amavasya would occur on the 5th day from their conversation (which is in Uttara Phalguni nakshatra).
However, Krishna replies that Amavasya would occur on the
7th day from then, in Jyeshta nakshatra.
This anomaly is echoed by Vyasa, who notes the Moon
"transgressed" Chitra. The word "transgressed" implies
unusual lunar movement.
The explanation: Karna's prediction placed Amavasya earlier
than expected, based on the Moon's phases.
