Perpetual Chinese Calendar

LunarCal  User's Guide - Add & Modify City Parameters

Note:

Starting with version 5.10, a new format city database is used - Location.DB. The old Location.Dat file is no longer used. If you have modified the old text database Location.Dat then you will need to re-enter the changes into the new database Location.DB.

After adding or modifying cities, you must hit the SAVE button to save the data to the database. Hitting the OK button only will save the new information for current session's use. You must go to the menu and save the Database for the changes to be permanent.

LunarCal now allows a graphical interface to add a new city. City and Country names should be non-blank. LunarCal does not check for duplicates. You may safely ignore the Type parameter - Radio, Infrared & Laser - these are just notes describing what type of observatory the location is. 

If you do not know your location's longitude and latitude you may visit the following sites:-

It is important that you enter the correct latitude & longitude for your required location or else the calendar may not be correct. This is especially so for the display of moon phase, rise & set times and moon compass. However, the enumerated Chinese calendars are always accurate regardless of the selected location.

Modify Existing City's Parameters

You can modify / change the parameters of any city.

Deleting a City

You can also delete unwanted cities to remove clutter.

All the changes you make is kept in PC memory temporarily and is lost when you exit the program. If you want to keep the changes made, you must save the database by clicking "Save Database"
