Show mohammedan year has ha 12 i months month 29 and 30 days day unlike ours the mohammedan calendar is a lunar one it I 1 you count the time it takes the moon to return to any phase yoo you will find that it is twenty nine and one half days known as the synod ic or often merely the lunar month many calendars have used this period in their reckoning be A cause the changing phases of the moon in the sky afforded a convent conven conven 1 bent means of telling the days observes a writer in the kansas city star I 1 the mohammedan year has 12 months alternating between 29 and 30 days making the average the correct length every month starts with the new moon as it first appears in the west after the sunset then first quarter full moon and last quarter mark the tour four weeks ot of the month but twelve 29 day months total only days which is eleven days short of the year consequently this means that mohammedan dates shift around through the seasons for instance the mohammedan year will commence in 1955 in the autumn and in 1971 it will again come in march thus their calendar gains a whole year on ours every 33 years no doubt we should find this very inconvenient not knowing what season a certain date might be in but in their countries it is very arid with little change between the seasons the gregorian calendar which we re use keeps step with the sun and ignores tho the moon but it is possible to have one that will keep in step with both A good example is the jewish calendar ordinarily the jewish year i is practically the same as s the moslems but after approximately three years when it has lagged a month behind an extry extra month is inserted which brings it up again actually there are seven of these 13 month years every 19 years year |
