Waawiita kiilhswa ‘Lost Moon’ appears approximately every three years. This lunar month is added to the end of the lunar year just after eehsipana kiilhswa ‘Raccoon Moon’, when all is dormant. While waawiita kiilhswa is not associated with any ecological changes, it is still a very ecologically important lunar month. Adding waawiita kiilhswa to the Peewaalia lunar year ensures that all ecological ties and occurrences take place in their proper months. Alignments and connections of seasonal and ecological occurrences are important to maintain in our Peewaalia community and with the Peewaalia lunar calendar. Pahsaahkaahkanka neepinwiki ‘summer solstice’ serves as our anchor point within our lunar calendar, as it must stay within the month of aciikatakiilhswa ‘Hilling The Corn Moon’. With the indication of pahsaahkaahkanka neepinwiki nearing the end of aciikatakiilhswa, we know waawiita kiilhswa needs to be added to the end of that lunar year. This results in 13 moons that lunar year.
