+Time Management Framework for PHP
+
+> The word aeon /ˈiːɒn/, also spelled eon (in American English), originally meant "life", "vital force" or "being", 
+> "generation" or "a period of time", though it tended to be translated as "age" in the sense of "ages", "forever", 
+> "timeless" or "for eternity".

+Aeon is a set of libraries that makes easier to work with PHP Date & Time in elegant Object Oriented way.
