My recent journal where I add only one line per day is based on the lunar month. Each page is either twenty-nine or thirty days from New Moon to New Moon. Both here and at camp I enjoy searching for the very first sliver of the waxing moon. Following that seven days later is first quarter, Full moon and ending with last quarter down to a disappearing sliver in the morning sky. So, if our cloud cover is sparse I will find the thin crescent of the new moon. That crescent is always in the evening sky.
