Your First Horoscope
You have just run ZET for the first time. Naturally, you want to see your own horoscope. This is what to do:
Select "World Atlas" and "All" from the middle and the right drop-down lists respectively. Then click in the left field at the top of the window and type the first letters of the name of a city, for example, liverp. In the cities list the blue highlighting bar should jump to the Atlas entry for Liverpool, England. If not (say you see instead 'Liverpool, New York, USA'), use the cursor keys to look thru the Atlas for your city. If your place of birth is not in the Atlas, you can try looking in the larger atlas: select your country from the top-right drop-down list, then select "World Atlas II" from the middle list. If this does not contain your place of birth either, for now choose the nearest large town - you can edit the Atlas later.
To select a city, double-click on the highlighted line, or press the Enter key. The Atlas window is closed, and you revert to the Event Data window, in which you can see that your selected city, its latitude (North or South of the equator) and longitude (West or East of Greenwich), and any time difference (if applicable - in the field labelled "GMT") have all been entered automatically for you.
Time difference - or Time Zone - is the number of hours by which local civil time at a place is ahead of (or behind) Greenwich Mean Time, which is the basis of calculations. For more information about this topic, see Your Location. NOTE: Time Zones are in European format, not American format. Easterly locations are indicated with a '+' sign, those west of the Greenwich meridian with '-'.
TIP: If next time you want this city, there is no need to use the Atlas. Cities that were selected for previous calculations will be recognised if you type their first letters directly in the City field. Or, make your selection from the drop-down list. (This list is called the Operational Atlas).
Make appropriate settings in this window: kind of interpretation (e.g. "For the displayed Natal Chart"), the output format (e.g. "Plain text"), the order (e.g. "Collate in house order") and others. Also you can select the collection of interpretaion sourses (books) from which the citations will be extracted: click "Library" button and proceed.
