All early calendars were lunar, and have now been replaced by a solar calendar. The calendar was originally invented by the women who made it lunar because it was precisely the ebb and flow of lunar rhythms that they were trying to track. You only need a solar calendar when you're doing agriculture because the work you do revolves around the seasons. And although hunting and gathering were also seasonal (depending on what game and plants were available in what season), this wasn't so much a part of primitive peoples' existence. They were vaguely aware of the yearly cycle, but didn't think in those terms much because they had no need to plan much of anything.
So why have a calendar at all, you might ask, much less a lunar one? The reason for this is because in those days, when the woman shaman, healer, and astrologer still ran the show, the human race was tuned in to certain vibrations, or laws of nature, which ebbed and flowed with the lunar cycle, just as agriculture revolves around the yearly cycle. That is, there are certain wavelengths of knowledge, or techniques for accomplishing things such as healing, music-making, hunting, fishing, gathering, weaving, love-making, etc. which oscillate on a lunar rhythm. Humankind has almost completely lost all of this knowledge; it survives in schemes of planting, etc. by the moon. All of these schemes are valid even if they apparently contradict, such as Europeans planting on a waxing moon near full, and Mayans planting just past new moon. It doesn't matter. The important thing is that the moon's phase be taken into account consistently, to hook onto the body of memory that exists "out there".
Just start by using a lunar astrology calendar, whether Jewish or Moslem or Chinese or whatever. A magician and astrologer can use a lunar ephemeris. Observe a seven day weekly cycle of activity with a 28 day month. The week as a unit of measure is a survival from this early Goddess religion calendar. Do the same things on the same days each week. Plan monthly activities by lunar phase. Schedule activities for e.g. the "second Tuesday" each month. You'll see a real difference in your feelings about yourself and the world, in particular your sense of belonging to the universe - your sense that the universe is nourishing and sustaining you - if you plan your activities around the moon's phase and sign. Women should plan their lives around their menstrual cycle and ritualize the time of menstruation (as the Hasids do). This is just a way of making a feeling or intuitive connection with a different channel of energy - a line of memory which is prior to the present "waking" line of memory - a truly joyous way of living your life.

The magician and astrologer is well-advised to look beyond simple sun signs to find the truth in astrology. Magicians and astrologers, like their ancient Goddess-worshipping forebears, look to lunar astrology for guidance.
