ACS Atlas Information
What it is:
The ACS Atlas is an enormous database of latitude, longitude and time zone change information for over 260,000 unique locations worldwide and is continuously updated by Astro Communications Services as political circumstances force changes in time change information. One of the leading causes of mistakes in birth chart setup is guessing inaccurately the time correction based upon time zone and daylight savings time info. In both Delphic Oracle and Timaeus, there is the capability to look up time zones, latitudes and longitudes based upon a time and place input through the ACS Atlas. If you calculate a lot of birth charts, it is highly recommended that you obtain this database.
How to obtain a license:
Visit Astrolabe. Note: Astro Communications Services has been renamed to its former name as set up by Neil Michelsen and is now located in Exeter, NH which used to maintain the ACS Atlas. Now this is maintained by Astrolabe. Users of Delphic Oracle and Timaeus can get the Atlas at the discount rate of $40.00 ($195.00 standard price), but if you have Solar Fire, Matrix Winstar, or Kepler/Sirius you may not need to buy a new Atlas, but just use the stand alone version that is on one of their CD's.
