Frequently Asked Questions

Before you email me questions, please read the web pages first - especially the "LunarCal" and "User's Guide" pages which explains the LunarCal program and various terms used. These pages should answer 99% of all your questions.

 

Q Why don't you reply my email?
A Hotmail accounts will not get any reply - why?  click here! In addition, majority of Hotmails are spam mails.

Lazy questions like - can you please tell me when Chinese New Year will fall on year XXXX? - You are suppose to download and use the program. I am not an online encyclopedia.

   
Q What is LunarCal?
A LunarCal is a 160-years perpetual Chinese Calendar program. It is "Charityware"  and is available for free download. This program will run on Win9x / ME / NT / XP based computers. You download the program and run it on your PC and it will tell you the dates of Chinese New Years and major Chinese festivals for years 1900 thru 2060.

It may run on some Linux computers - see "Wine" below.

   
Q I cannot execute the program after downloading it.
A Check the MD5 checksum as provided on the download page. If it does not agree then you have to download again - maybe using a different FTP program or use another PC. The programs have been downloaded by many using a variety of FTP programs and browsers (IE & Netscape, etc) and have experienced no problems.
   
Q What is MD5?
A MD5 is a message digest algorithm. For more info visit:-
http://www.rsasecurity.com/ or search Google.
   
Q Can you send me the source code?
A Don't ask.
   
Q Can you tell me when Chinese New Year falls on the year XXXX?
A Download and execute the LunarCal program. Right click on mouse to pop up menu. Then select your required date.
   
Q How can I obtain information for years prior to 1900 and years beyond 2060?
A LunarCal currently does not cover these years. The astronomical algorithms implemented works best for years 1900-2060. The JDE2000 epoch formulae are used and will not be accurate for years far beyond 2060. I expect to see some minor corrections for various formulae as time goes by. This is especially so in the Delta Time calculations.

Also, from the early days of the Chinese calendar up to about 1900, there were a number of changes to the calendar rules by the Chinese authorities thus making it difficult to enumerate such a calendar. 

Moreover, majority of software (including OS) are unable to handle years beyond 2030 and/or 2059 due to limitations in their design of the datetime structure. This is especially so in MS Visual C.

   
Q Where can I get a Chinese Calendar for year XXXX?
A Go to the Calendar tab and follow the subsidiary tabs and you should be able to download the full printable lunar calendar for the current year. You may wish to search www.google.com 
   
Q Can you tell me the meaning of ??? Chinese characters on LunarCal?
A This site is about Chinese calendar and only LunarCal's main screen is in Chinese, other screens are in English. On the web pages you can find  pages containing English translation of the various Chinese characters used. The LunarCal program also has screens of Chinese characters with the English translations. Please read the online manual LunarCal Online Users Guide
   
Q How can I query when Chinese New Year falls on a particular year on your web site?
A At present, this is NOT an interactive web site for you to query Chinese New Years online. There are many other such websites available.
   
Q How can I find the equivalent Gregorian calendar date corresponding to a Chinese Date (vice versa)?
A At present there is no straight forward technique. The only method possible in current version is to set the LunarCal datetime:-

(1) To Convert from Gregorian date to Chinese date:
Enter the required date in the "Set DateTime", "Set Local DateTime" dialog and then "Display", "Chinese Lunar Calendar". Then look at the Gregorian date entry: eg: Gregorian date Feb  25, 1965 = Chinese date 1st lunar month day 24.

(2) To Convert from Chinese date to Gregorian date:
Use above technique to enter the required date - using the Chinese date as a 1st trial for the Gregorian date. Eg: Chinese date 12th day of the 4th lunar month 1982. First enter a Gregorian trial date as day=12, month=4, year=1982. The Chinese Lunar Calendar displays lunar month 3 which is incorrect. Just hit [DnArrow] or [UpArrow] key to display the correct lunar month. In this case its lunar month 4, then look at the 12th day (Chinese) giving a Gregorian date of May 5, 1982.

The technique works since in majority of cases the Chinese date is approximately 1 month (at most 2 months) off the Gregorian date.

I shall put this on the "to do" list for later version.

   
Q Will you make available a PDA version?
A I have decided not to port LunarCal to the PDA platform.
   
Q I have "Wine" but I cannot run LunarCal?
A You very are lucky! There are lots of people including myself, who have not been able to get a proper install of Wine at all. The last version that I check out - wine-20020605.tar is buggy. The HowTo manual is out of date  and the program does things differently. There may be a later release by now. I have already given up on Wine. I suggest you get assistance from the wine newsgroup. Check out www.winehq.org
   
Q Can you tell me where I can where I can get more information on XXXXXX?
A Have you tried the popular search engines? www.google.com   www.yahoo.com   www.ilor.com   www.askjeeves.com  www.alltheweb.com  http://vivisimo.com/
   
Q Can you tell me more about the year of the Horse (or any other animal year)? (Horoscope)
A Unfortunately no. I am not a fortune teller. Please visit some fortune telling web sites.

For those interested, the book "The Handbook of Chinese Horoscopes" by Theodora Lau, ISBN 0 00 638875 2, Harper Collins Publishers, London, may be consulted. This is a great book with detailed descriptions (including personality traits) of all 12 animal signs.
