Incorrect, a lunar month is different to a solar month. The papal calendar has a continuous weekly cycle but the lunar cycle starts at the new moon. Please read the scripture and start paying attention to the new moons.
So you wish to see some verses do you, lover of papal calendars.
Psalm 81:3
Saying, when will the new moon be over so that we may sell grain; and the sabbath, so that we may offer wheat for sale?
See that LGW, the new moon is the same as Sabbath, no one works on the new moon.
Ezekiel 46:1
Thus says the Lord God, “The gate of the inner court facing east shall be shut the six working days; but it shall be opened on the sabbath day and opened on the day of the new moon.
Once again, the new moon is the same as a Sabbath.
Amos 8:4-5
Hear this, you who swallow up the needy, and make the poor of the land fail. Saying: "When will the New Moon be past, that we may sell grain? And the Sabbath, that we may trade wheat?" Making the ephah small and the shekel large, falsifying the scales by deceit.
Yet again, no business on the day of the new moon.
2 Kings 4:23
So he said, "Why are you going to him today? It is neither New Moon nor Sabbath." And she said, "It is well".
Well you can't wander off except on a rest day and the new moon and the Sabbath are the same.
What Scripture does provide is indications that each month was 30 days in length.
- The chronology of the Flood appears to depict 30 day months. The passing of 150 days (Gen 7:24) appears to take us from the 17th day of the 2nd month (Gen 7:11) to the 17th day of the 7th month (Gen 8:4).
- The biblical account of the departure from Egypt to the declaring of the Mt Sinai commandments can be viewed in such a way to show the first and second months of God's calendar for that year were composed of 30 days each.
- Prophetic texts in the book of Revelation suggest 3.5 times(years) would equate to 42 months or 1260 days.
- In the book of Daniel the 'seven times' of Dan 4:16 has been explained as shadowing a greater prophetic period of 2,520 years, that is 7 years of 360 days per year.
- Other prophetic periods are also divisible by 30,
Ezek 4:5 - 390 days (equals 13 x 30 days)
Dan 12:11 - 1290 days (equals 43 x 30 days)
Dan 12:12 - 1335 days (equals 44.5 x 30 days)
Where is the new moon in your calculations?
You know full well that the calendar of the Hebrews was a lunar calendar. The papal calendar did not arrive until the sixteenth century.
You have nothing to work with.
