The Wenger Sundial is custom made for the users location on the earth. The latitude and longitude of the location where the dial will be used determines where on the globe the scribe lines are placed. The latitude and longitude may usually be determined by the address of the user, if within the United States. Placement of an order for the dial needs to have enough information to determine the latitude and longitude of the users location.
As well as the latitude and longitude, the local time zone needs to be known. This is given by the time difference between local time and Greenwich time.
The use or lack of use of daylight savings time needs to be specified.
Some users prefer 24 hour time lines instead of the typical 12 hours lines.
Some custom scribing may be done by special request.
Normally the Wenger Sundial is shipped within four to six weeks of the order date.
