The Chinese Lunar Calendar is a lunisolar calendar, consisting of months corresponding exactly to lunar cycles and years which stay more-or-less in sync with seasonal years. The structure of the calendar depends on the exact times of certain astronomical events, principally dark moons and winter solstices. The solar calendar consists of a series of seasonal years which are divided into 24 "solar terms". The lunar calendar consists of a series of years which are divided into 12 or 13 lunar months. A solar year always begins at the (northern) winter solstice. A lunar month always begins on the day of a dark moon. Chinese Calendrics is used to do the following: To convert between dates in the Chinese, Vietnamese and Japanese solar and lunar calendars and dates in the Common Era and Julian calendars. To calculate the date of New Year's Day in the Asian lunar calendars. To ascertain the Western dates of the starts of all lunar months in a year in the lunar calendar. To find leap months in the lunar calendar. To find the Western dates corresponding to Chinese, Vietnamese and Japanese anniversaries (e.g., birthdays). To move forward or backward from a given date (and time) either by a period such as a month or by a number of days. To calculate the phase of the Moon for any time within a 6000-year period. To search for the next or previous full moon, dark moon, lunar quarter, solar term or solstice or equinox of a certain type. To search for a solstice or an equinox in combination with a dark moon or a full moon. To search for the next or previous day, month or year with a certain element-animal correspondence (e.g., the next water-ox year or the next fire-dragon day). To find days for which the element-animal is the same for day, month and year. To see an entire month inthe Chinese lunar calendar showing images of the Moon for each day.

'Hermetic Systems' is the business name of Peter Meyer, [email protected], the developer of this software, and the owner and maintainer of the 'Hermetic Systems' website. The 'Chinese Calendrics' software ("the Software") consists of the executable file and the other files installed by the installation program obtainable from the 'Hermetic Systems' website (including any future versions). The Software is protected by copyright, which is owned by Hermetic Systems. The Software may be downloaded from the 'Hermetic Systems' website or another authorized download site solely for the purpose of its evaluation with regard to the purchase of a user license. Neither the installation program nor any work derived from it may be distributed further by any means (including via CD or the web) without the permission of the copyright holder. All intellectual property rights related to the Software are owned by Hermetic Systems. You may not rent or lease the Software. You may not modify, translate, reverse engineer, decompile or disassemble the Software or any part thereof or otherwise attempt to derive source code or create derivative works therefrom. You may not remove, alter or destroy any proprietary, trademark or copyright markings or notices contained within the Software. You may not sell or offer for sale any derivative work. Any rights not explicitly granted by Hermetic Systems are reserved. In return for a license fee paid to Hermetic Systems or to one of its authorized representatives or resellers you are granted a license to use the Software in its fully-functional form and you are provided with activation keys for each installation of the Software as follows: (A) If you are a natural person then you receive a single-user license and this entitles you to install, activate and use the Software on a reasonable number of personal computers (e.g., a laptop and a desktop) in your household or office. (B) If you are an entity other than a natural person (e.g., a corporation or a government agency) then you are required to purchase a number of single-user licenses equal to the maximum number of persons who will be using the software at any one time. For some programs a site license (a.k.a. a group license) is available. The function of an activation key is to remove any temporal or functional limitations on a particular installation of the Software. A separate activation key is required for each installation (in other words, an activation key works only on a particular computer). For some programs there are three types of user license: 3-month, 1-year and time-unlimited (a 'perpetual' license). 3-month and 1-year licenses allow use of the software for the stated period beginning on the date of purchase of the license. At the termination of the license period the software will revert to a functionally limited trial version. It may be reactivated by purchasing a new license. In the event that a later version of the software is released, you may update an installation at no charge by downloading and installing the new version. If you change your computer (or make a major hardware modification) you may need to obtain a new activation key. This can be obtained in the same way as before (and at no charge), provided that, in the opinion of Hermetic Systems, the number and frequency of such new activation keys is not unreasonably excessive. A user license is not transferable. That does not mean that you cannot get an activation key if you transfer the software to a new PC. It means that you are not permitted to transfer the user license to another person. Installation of the Software constitutes an agreement that the Software is provided "as is", without any warranties or guarantees. Hermetic Systems makes every effort to ensure that the software is error-free and performs as stated in the online user manual, but does not guarantee this. You assume responsibility for selecting the Software and using it for your intended purposes. In no event shall Hermetic Systems, its resellers or distributors of the Software be liable for any any damages whatsoever arising out of use or inability to use the Software, even if advised of the possibility of such damage
