(*Note: Lunar months are difficult to calculate exactly, especially considering that one common traditional method of determining the new month is an observation of the waxing crescent. I have opted to calculate the exact time the moon reaches 2.2% illumination (at which point it is generally visible at night), then call the Gregorian Date at that timestamp the first day of the month. You could argue for some timings of the visible crescent being the next day or the previous day. And you could also have, say a 1.2% new crescent that's visible at 11:59 or invisible until 12:01 and that throws it off by a day too. Well, I had to pick some method here so that's what I did. Except I used 2 AM instead of 12 AM to avoid issues from daylight savings time.
Moreover, the ~0.37 fractional lunar months each year will frequently require a 13th intercalary month in a year, the human methods of calculation for this are quite varied. I have chosen to use a simple cutoff of 13th moon before the Gregorian Date (12 AM midnight) of the Spring Equinox = a 13 month year, 13th moon after 12 AM of Spring Equinox = a normal 12 month year.
The most confusing case versus other calendars, by this method, is when the new moon is just around midnight of the spring equinox. Some calendars will call it 12 months, others 13. So it's not uncommon for some types of lunar calendars even among the same culture to be off by a month of each other in some years if they decide 13-month years by two different methods. Which is also the case here.

(**: It goes without saying that biblical holy day calculations are also approximate and will vary across denominations. Which is the right day, and whose is the right calendar? Well, if God appears to observe a high holy day about a day's difference from you, as in the case of Christ's Passover Communion being a day before the Passover of the Pharisees when they pierced The Lamb, then in that case you are doing sunrise or new moons a little off. But woe if you see God observe one of His high holy days a month off from when you think it is — this means you have allocated your 13-month years incorrectly! The ultimate tiebreaker for which of the various determination methods to use is authority.)
