Name of the calendar used in naming a date such as a publication date, for example, “Gregorian”, “Japanese” (Emperor years), or “Thai Buddha”.


In this Tag Set, many of the date elements, such as <pub-date> and <year>, may take a @calendar attribute to indicate the calendar in which the date is given. For example, a calendar might be named as:

Here is an example of a year and calendar in Pinyin:

<year calendar="Nónglì">Guisi</year>

Neither a date not a calendar need be stated in English. The element that holds the @calendar attribute may also take an @xml:lang attribute to name the language or script of the element content. For example, here is a year from the traditional Chinese calendar, in which both the @calendar and the year itself are given in Chinese:

<year xml:lang="zh" calendar="農曆">癸巳</year>
