Charting and Printing Instructions

Directions For Entering Chart Values:

  1. Most values are self-explanatory.
  2. For "Date of Birth", enter the month, day, and year in which you were born (replace "1900" by the appropriate numeric value, e.g. 1951 or -54).
  3. For "Time of Birth" enter the hours, minutes, seconds and time zone.  You need to know what time zone was in effect on your birthday.  For example, New York City is in a time zone 5 hours west of Greenwhich Mean Time when Eastern Standard Time is being observed but 4 hours west of Greenwhich Mean Time when Eastern Daylight Time is in effect.  So according to which day you were born on you would select either "w05:00 EST / CDT" (5 hours west, which can be either Easter Standard Time or Central Daylight Time) or "w04:00 AST / EDT" (4 hours west).  On the other hand, if you're really old and were born in New York on 1800, then you would need to know that "Local Mean Time" was in effect then and you should make that selection.
  4. For "Latitude" enter degrees (0 - 90), followed by 'N' (for "north") or 'S' (for "south"), followed by minutes (0 - 59).
  5. For "Longitude" enter degrees (0 - 180), followed by 'E' (for "east") or 'W' (for "west"), followed by minutes (0 - 59).
  6. Click on "Compute".
