A "lunar month" is 29.5 days, so with the traditional school year, you are in school about 10 lunar months each year.
Sunspot cycles are 10 to 12 years in length.
Ramadan is based on the Islamic lunar calendar because the lunar year is about 10-12 days shorter than the Gregorian calendar, which is based on the solar year. This causes Ramadan to shift by about 10-12 days earlier each year in the Gregorian calendar.
A solar year lasts approximately 365.24 days. A lunar year lasts 354.37 days. The difference between the two is 10.87 days, or 10 days, and nearly 21 hours.
Your 1 kilometer equals 3.24077649 x 10-14 parsecs. And your second equals 3.16887646 x 10-8 years. Converting kilometers/second to parsecs/year involves multiplying by 3.24077649 x 10-14 and dividing by 3.16887646 x 10-8 to get your answer. Or do that bit of math in advance and then just multiply by 1.022689439 x 10-6 to get your answer. Make sure you have your beginning figure in km per one second. Your answer will appear in parsecs per one year, or just parsecs per year.
No. During the 5000-year period 2000 BCE to 3000 CE, there have been / will be a total of 12,064 lunar eclipses ... an average of about 2.4 per year. During the 10-year period 2001 to 2010, there are 24 lunar eclipses ... also 2.4 per year. There were 3 lunar eclipses in 2001, and 4 lunar eclipses in 2009. December 21, 2010 is/was the second lunar eclipse of 2010. So over the long term, you're looking at between 2 and 3 lunar eclipses every year.

Sunspot cycles are 10 to 12 years in length.
1000 Hz means 1000 cycles per second, which is more than 10 cycles per second. Please note that this has nothing to do with "fast" in the sense of "speed".
It changes. There are three lunar eclipses on December 10, 2011, June 4 and November 28, 2012. Over a period of several years, solar and lunar eclipses both average about 2.3 per year, but anything up to 5 in a year is possible.
according to my text book "10^9 cycles per second. "

March 10, 1964, corresponds to the 18th of Jumada al-Thani in the Islamic year 1384. The Islamic calendar is lunar-based, and this conversion is based on the differing lengths of the solar and lunar years.
The frequency of the electric generator is 60 Hz, calculated by dividing the number of cycles (600) by the time it takes (10 seconds) to produce them. Frequency is measured in Hertz, which represents the number of cycles per second.
