2. If more precise information is needed NASA has exact eclipse and moon phase data worked out for the entire century.
3. Time Zone is the number of hours the local time zone is offset from UTC(GMT), negative to the west and positive to the east.
Standard times are EST=-5, CST=-6, MST=-7 and PST=-8.
Daylight times are EDT=-4, CDT=-5, MDT=-6 and PDT=-7.
4. Lunation count starts with the first new moon in 2000 (1/6/2000) equals zero. Brown's Lunation Number is 953 greater.
5. Based on an algorithm developed by Jean Meeus (Astronomical Algorithms 1998).
