Christians are celebrating their Easter (supposed to be the resurrection of the Christ) with eggs. Colored, painted and hidden eggs.
Comments from Ricky Maestrado:
Like Halloween, Santa Claus, and even Sinulog are among the many pagan traditions adopted by early Christians just because it falls on the same time of the year as with another Christian event. (And also back then, it would be easier for them to convert the local non-believers if they could show that Christianity is somehow connected with their traditions.)
The bunny, eggs, chicks, even lambs and daffodils are all to do with the spring season which symbolizes rebirth like the resurrection of Jesus Christ.
The influence in the Philippines, however, is due to commercialization and has nothing to do with religion.
