What term refers to a calendar used in Buddhism for determining the timing of casketing?

The term that correctly refers to the calendar used in Buddhism for determining the timing of casketing is the Buddhist Almanac. This almanac plays a vital role in Buddhist practice as it provides a detailed account of important dates, festivals, and rituals that are integral to the spiritual life and community events within Buddhism.

In the context of casketing, which involves the preparation and timing of funeral rites, the Buddhist Almanac offers specific guidance on appropriate timing and observances according to the lunar calendar and Buddhist traditions. It helps practitioners align their activities with auspicious dates, ensuring that rituals are performed at the most spiritually beneficial times.

The other provided choices do not accurately convey this specific purpose within Buddhism. For instance, a "Book of Dates" is too general and does not refer specifically to Buddhist practices. A "Ritual Calendar" could imply a broader set of rituals not limited to Buddhism, and a "Casting Calendar" does not have recognized significance in this context. Thus, the Buddhist Almanac is the most precise and relevant choice.
