The above are the days of the lunar fortnight as found in Rág Bilawal. Most of the names of the days are easy to understand. Only ‘khastí’does not sound like anything to do with six, the names of the other days are clearly linked to their number. I do not know why there are two different days 12.
The first fortnight of the lunar month runs from full moon to no moon, the second from no moon to full moon. The Vikramí year is a lunar year, but the Vikramí Calendar has extra days to come near the solar year of 365.25 days.
The Muslim calendar (Hijra) is a pure lunar calendar, and the seasons move across the calendar every year. In the Middle East and South Asia, where the difference in the length of the days in summer and winter is only small, this has only limited effect on the length of the fasting during Ramzam. In Scandinavia the fast will be very long when Ramzam falls in July. Anybody with more knowledge of lunar calendars, please share !

1.ádit vár 2.somvár 3.mangal 4.budvár 5.vírvár 6.sukrvár 7.chhanichharvár.In this sabad Guru calls Sunday ádit vár and Tuesday mangal, without ‘vár’. The sat vár (seven days) sabads suggest that in the days of our Gurus there was also a solar calendar in use. Equally I am under the impression that there were more lunar calendars than just Al Hijrá and Vikramí.
I read on a Hindu website that Vikramí did not start with Chet as in the two Twelve Months sabads in the Guru Granth. Or are the Twelve Months sabads based on another lunar calendar ?
To add to calendar confusion we will end with the ‘Christian’ (Anno Domino = the Year of our Lord) or Common Era Calendar. The last four months are September, October, November and December. That means 7th, 8th, 9th and 10th Month, which suggests strongly that at some time in the past this year must have started with March.
