This Luni-solar calendar [LSC] is based on each month, or lunation, beginning at dawn following the moon's conjunction with the sun. The first day of each month is called New Moon Day and is observed by abstaining from common labor and in worshipful consecration of oneself to Yahuwah, the Creator. Each month consists of either 29 or 30 days. In the 30 day months, the last Sabbath is followed by translation day, then New Moon Day, both of which are not counted as part of any week. Four complete weeks of seven days follows: six days of work, then the Sabbath which always occurs on the 8th, 15th, 22nd, and 29th of the LSC months.
These LSC dates can fall on any day/date of the Gregorian calendar which, unlike the Creator's calendar, uses a continuous weekly cycle. If the LSC New Moon day falls on a Mo-day, the following four Sabbaths will also fall on Mo-days. From month to month (lunation to lunation), the New Moon Days and Sabbath Days will fall on different Gregorian days/dates and, consequently, will appear to 'float' through the Gregorian calendar.
The New Year begins at dawn following the first conjunction that takes place after the spring (vernal) equinox. On years when the 12th lunation finishes before the vernal equinox, an extra intercalary month, the 13th month, is added. Over a series of 19 solar years, these 12 and 13 month years will correct for any deviation from the solar year. There are seven thirteen-lunation years in every nineteen years; this is called the Metonic Cycle. This makes the calendar truly luni-solar; the lunations are adjusted to the solar year. These adjustments are somewhat similar to the extra day in the leap year of the Gregorian calendar.
New Moon celebrations were observed as a Holy Day, though with less strict observance than that of the regular Sabbath. The 30th of a month was a transition from one month to another, a dark day which we now call translation day as mentioned above, and was a regular work day not considered as a Holy Day or feast day. (I Samuel 20.)
To use: Once New Moon Day has been determined, simply fill in the planetary days of the week, (Sunday, Monday, Tuesday, etc.) at the top of that month, and the corresponding dates of the Gregorian calendar for the remaining 29 or 30 days. This calendar is perpetual as all months and years will be the same, only the days and dates of the written-in Gregorian will vary.
Fear the Eloah of Creation and worship Him on the days He has sanctified. Let us all preach the Sabbath more fully.
