GMM Episode Gaps

A while back, I noticed that celebration episodes on GMM (500th episode, 700th episode etc.) were on Thursdays and not on Fridays as one would think. This bothered me a lot so I made a timeline-esque thingy to find the discrepancies  in episode numbers and airdates. Below is the timeline-esque thingy just in case anyone else was bothered by this (it's quite boring though). BYMB!

• Monday January 9th 2012 - 1st Episode (episode 1)
• Wednesday January 18th 2012 - No episode due to protesting against online piracy (Supposed to be episode 8)
• Thursday January 19th 2012 - GMM resumes (episode 8)
• Monday May 28th 2012 - 100th Episode (episode 100)
• Monday November 12th 2012 - 200th Episode (episode 200)
• Tuesday September 3rd 2013 - Season 4 Starts (episode 275)
• Tuesday October 8th 2013 - 300th Episode (episode 300)
• Wednesday January 8th 2014 - Season 5 Starts (episode 354)
• Thursday March 13th 2014 - 400th Episode (episode 400)
• All "celebrations" from March 13th 2014 are on Thursdays
