Unfortunately for both you and me, the Easter Eggs came a couple of years ago for a Easter Event and once they come around, they can't come around again. :( But luckily we have three events coming up in the next three months. The Halloween event which will start this week at sometime, the Thanksgiving event, which will start sometime in November, and the Christmas event.
Have patience, it's not Christmas yet. And by the way, I don't know.
all of the largly celebrated holidays Halloween, thanksgiving, Christmas, and Easter all have an event that start about 2 weeks before the actual holiday and end about 2 weeks after the holiday itself has past.
The runescape Christmas event will start between Dec-17 and Dec-19. There is a complete guide for the event with walkthrough and pictures in this website, http://runescape-quest.info/runescape-Christmas-event-2008-2009-guide-and-help-with-wiki/
The Halloween events usually start approximately one week before the Holiday. Same with Thanksgiving and Christmas.Keep an eye out on Runescape for the event...
Read the news post about it properly, and it will tell you what to do.

It starts sometime before Thanksgiving and continues a few days afterwards.
