Onyx is the birthstone for December in the old Tibetan calendar. This December birthstone is also the zodiac stone for Capricorn, as well as the zodiac signâs talismanic stone. Onyx is a banded chalcedony of black and white, though black is the December stoneâs most popular color.
2080 is full time, 40 hours per week, 52 weeks per year. 2000 considers the 10 national holidays. 1980 is the figure that is being used in the acquisition which I am supporting. I questioned the rationale of using 49.5 weeks (1980/40) as a Person Year because it not only breaks a week in half, it breaks a day in half.
Based on a 30 hour work week how many hours per month? Ignoring statutory holidays and the variation of days in a month, you could work it out this way:-    there are 52 weeks in a year-thus 30*52 = 1560 hours a year.  â¦  there are 12 months in a year-thus 1560/12 = 130 hours a month.
