Easter
It is: TODAY
Today (considering you'll read this answer today).
A date or Today
If you write April 26, 2011, this contains only 5 letters, but unfortunately also contains numbers...
To write 24 January 2014 in 5 letters without using numbers kindly write 24.1.14.
Even if you used roman numerals, it would still require more than 5 letters.
