How did you calculate this??

80 years = 29,220 days (80 x 365.25 = 29220)
Mean synodic period of moon: 29.53 days
Number of full moons in 80 years: 29220 / 29.53 = 989.5
So it would be either 989 or 990, depending on the phase of the moon at the time of your birth.

this is how to calculate: 1 year equals 365.25 days; a full moon happens every 27.32 days; so 80 years = 1069 full moons, that is of course if a person already observes the moon from the time he/she was born. but a person usually witness a thing by the age of 3 or 5 years.... so just minus the number of full moons for the period that he/she cannot still observe the full moon and you get the correct answer.

1 a month for 1 year equals 12 times 80 years equals 960

About 990 full moon days will go by. Here is how I got that figure:
Each year is 365.25 days approximately. So 80 years is 29220 days. And the lunar month is approx. 29.5 days. So divide 29220 by 29.5 and we get 990.5 or 990 full moon days.

*wink* witness?
hmm? depends on if they are outdoors to witness it or not.. I guess if they are a hermit and never venture outdoors, they will not witness even 1 full moon...

about 960 depends on the night if it is clear or not
