How many days are in 19 lunar calendar years with an extra month added in seven times?
In the lunar calendar system, a regular year consists of 12 lunar months, totaling approximately 354 days. When an extra month is added seven times over 19 years, this results in a total of 19 x 12 + 7 = 235 lunar months. Converting this to days gives us 235 x 29.53 (average length of a lunar month) = approximately 6946.55 days.

How many lunar months are there in a solar year?
Approximately 12, but 12 lunar months are a little less than a solar year. In China, both lunar and solar calendars are used, but the lunar New Year does not fall on the same date of the solar year all the time. Occasionally they have a 13th lunar month to bring them back into alignment.
Why are there not 13 months?
The "month" was originally invented in an attempt to split the year up intoslices that match the moon's cycle of phases.In one year, the moon goes through its complete cycle of phases 12.368 times.That's closer to 12 than it is to 13. So, even though the system never reallycaught on, 12 months in a year still stay closer to paralleling the moon's changesthan 13 shorter months would.To look at it from a slightly different angle:-- The moon does a complete set of phases every 29.531days.-- 12 months in a year would average 30.44 days each ... 0.91 days long.-- 13 months in a year would average 28.1 days each ... 1.44 days short.The 12 months come closer to tracking the moon's cycle, even though nobodycares any more.You may be interested to know that since there are 12.368 lunar months in a year, if there were 12 lunar months in a year then every 3 years or so there would be the need for an additional month - a kind of lunar Leap month. The Hindu lunar calendar does have several leap days and occasional leap months to allow for the mismatch between the lunar month and the solar year. Unfortunately, the calculations for these additional days and months are not the easiest to understand.

How does a 12-month lunar calendar differ from your 12-month solar calendar?
A 12-month lunar calendar is based on the phases of the moon, with months around 29.5 days long, making a total of about 354 days in a year. A 12-month solar calendar, like the Gregorian calendar, is based on the Earth's orbit around the sun, with months averaging 30-31 days and a total of about 365 days in a year. This results in a discrepancy in the number of days between the two types of calendars.

How long is a moon year?

Why is the some of the months different?
The idea of months began as "Moon Cycles"... and thus the term Months from the word Moon.A lunar month, however has 29.53 days, and a solar year has 365.242 days...So the seasons would shift slowly with calendars based on 12 lunar months (and you would still have either 29 of 30 day months to compensate for fractional days in the lunar cycles).But, perhaps because the moon (lunar) cycles were previously used, 12 months were chosen for the calendar.365 days / 12 months = 30.416 days.Thus to divide a year into 12 calendar months with full days (fractional days don't work), the number of days per month have to be varied slightly.The approximately quarter day per year "extra" is compensated for by adding an extra day every 4 years on the leap year, with more complicated rules to compensate every centuryAlso see the Wikipedia articles on the Tropical Year that our calendar is based on, and the Sidereal Year which the procession of the equinoxes is based on.
