Plan Your Epitaph Day is observed on April 06, 2018. The day is a chance for control freaks to plan out what their gravestone is going to say. An epitaph is a short text honoring a deceased person, strictly speaking that is inscribed on their tombstone or plaque, but also used figuratively. Some are specified by the dead person beforehand, others chosen by those responsible for the burial.
An epitaph may be in poem verse; poets have been known to compose their own epitaphs prior to their death, as William Shakespeare did. Most epitaphs are brief records of the family, and perhaps the career, of the deceased, often with an expression of love or respect - "beloved father of ..." - but others are more ambitious. Some are quotes from holy texts, or aphorisms. One approach of many epitaphs is to 'speak' to the reader and warn them about their own mortality. (With material from: Wikipedia)
