AliceWhat you are not getting is that time zones--as in +7 or -5, will not give an accurate chart---but only an approximate chart. The actual sun time in any given zone varies from 30 minutes less to 30 minutes more than the Zone reflects. Time zones were created by the railroads for the convenience of travelers. That have nothing to do with astrology and will produce only approximate charts that can be off +/- 30 minutes and as much as 15 degrees on the Ascendant.Check: Larousse Encyclopedia of AstrologyandThe Only Way to Learn About Astrology: Volume II------------------You are a blessing and you are blessed.

Of course, that's the easiest way. But I want it to be accurate too. Eager to know what to do. For example: What if you were born at 8:40pm in New Jersey? What would you do Rev. Alice? And then we can go in and compare. Or provide any other example which we can go in and compare to see what happens.So eager to know!

The only reason to set manual timezone to 'LMT' is when you enterbirth date from before the introduction of timezones, e.g. from before1880 (exact data depends on country).
Even then, our system knows when timezones were started in each country, and does this automatically anyway.
Therefore there is no reason EVER, except for experiments, to set themanual timezone mode.
Unless you prefer false charts.
There is no room for opinion in the area of calculations.
The degree of the ecliptic rising in the east (aka Ascendant) or thedegree of the eclipitic crossing the meridian (aka MC) at a given placeand time is a FACT OF NATURE. Only one result is true, and this is ours.

If we do NOT use LMT:August 20, 199612:00 PMChicago, IL
