Some people's lunar calendars are set up so that the beginning of every month (new/sliver moon) will always be the beginning of the week (Sunday) making Saturday (the 7th day) the sabbath and end of week. A problem I personally have with this thinking is what do you do with the extra days at the end of the month since a lunar month is 29.5 days?

Say you round that 29.5 up to a 30 day month like the following (the yellow cells are the sabbath):
Sun Mon Tue Wed Thur Fri Sat
1 2 3 4 5 6 7
8 9 10 11 12 13 14
15 16 17 18 19 20 21
22 23 24 25 26 27 28
29 30
1 2 3 4 5 6 7
So what do you do with the extra days 29 and 30? Do you add them to the end of the previous week or the beginning of the next? And regardless, what day of the week do you call these days?

If the end of the previous week, then would they become sabbath days too so you have 3 sabbath days in a row (and a mini-vacation since you can't work on a sabbath day)? Would they fall on Sat2 and Sat3 days of the week?

22 23 24 25 26 27 28 29 30
1 2 3 4 5 6 7
If day 29 and 30 are not considered sabbath days, then that means you have a period of 9 days from sabbath to sabbath

Or if you add them to the beginning of the next week, then you've got 8 days of work and you rest on the 9th (going against what the bible says to work 6 days and rest on the 7th). Would they fall on Sun2 and Sun3 days of the week?

    15 16 17 18 19 20 21
    22 23 24 25 26 27 28

If you attempt to solve this problem by saying that a month only has 28 days, then you now have a new problem since you'd need add a 13th month to get 364 days in a year. In addition to this, you no longer have a pure lunar month since the months later in the year no longer start on a new/sliver moon since a lunar month is 29.5 days not 28. This means that by the 13th month, it would start closer to a full moon than a new/sliver moon.
