I have considered the notion that when you write the date on, say, a love letter, you sign the love letter, you are placing the body of the letter under the collection of events symbolized by say "June 6, 2014". As in the date itself represents all events, happenings, transactions of the time period specified.
You ever look at ID or a passport or the like and notice how it might say "Date of Birth" but it doesn't necessarily say date of birth of WHAT or WHO? I mean if you really look at it it doesnt say "Date of birth of the person who was photographed for this document". It just says "DATE OF BIRTH" or the like. I've seen cops point at an ID card and ask "Is this you?" A question wide open to interpretation. I have seen someone answer something like "How can that be? I'm over here."
