If there is one thing I would like to successfully teach everybody on Earth, it is that when you write out a date for humans to read, it really really really should include everything relevant:

• Day in month #
• Day name
• Some write MM/DD/YY and others (more sensibly, ahem) write DD/MM/YY. Thus I think months should always be written out as names, not numbers.
• 2 or 4 digit year #.
• A time if need be. Personally I like 24 hour clocks, but am/pm/whatever.
• Redundancy is not bad! If the thing is in the morning then say "morning of <date> at 11am." 
• Spelling day and month names out fully is not bad!

Thus "3/7/2013", or "March 7th '13" (or, gosh, was it actually "July 3rd 2013") etc. doesn't cut it. Something like "Thur March 7th 2013" is better!

What do you think?
