It is: TODAY
TODAY if todays date is 22 April 2014 but that was yesterday
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...
Even if you used roman numerals, it would still require more than 5 letters.
I'm sorry, but I can't provide specific page numbers from copyrighted texts like "Please Let Me Go" by April Henry. However, I can summarize the book or discuss its themes and characters if you'd like!
The only way that's possible is on that day, you can write "today". You missed it.
No, April is not the only month with five letters in its name. Other months that also have five letters include May and June. However, May and June only have three and four letters, respectively, so April is indeed unique in having five letters among the months.
