Krishna Navami of the Dark Fortnight

Krishna Navami is the twenty-fourth tithi overall, the ninth day of the waning fortnight, sharing the character of the ninth tithi and its dedication to the goddess Durga. In the fivefold grouping it is a Rikta tithi, generally reckoned unfavourable for new undertakings. The waning Moon is now past its last quarter, a thinning crescent rising before dawn. While the great Navami festivals fall in the bright fortnight, the ninth tithi of the dark half carries the Goddess associations too. These are the conventions of the calendar tradition, which reads each tithi through both its fixed number-character and the waxing or waning of the Moon in the fortnight where it falls.

The waning ninth's Durga association, carried over from the bright-fortnight Navami that closes Navaratri, has no major public festival attached to it in most regional calendars, and its significance in the panchanga is largely confined to its place in the fivefold classification as a Rikta tithi, generally counselled against for new undertakings, a caution applied here with no countervailing festival to override it, unlike the bright Navami where Rama Navami and the close of Navaratri routinely take precedence over the tithi's default caution.
