The dates provided are all accurate, if I have made any mistakes, please let me know and I will update asap.
There is a little speculation involved.
From the information provided in the May edition of GameInformer magazine, Halo 4 takes place 4 years, 7 months, and 10 days after Halo 3. Halo 3 was released September 25th, 2007. The dates below will have a large focus on Cortana’s age.
To get started with a few important dates:
November 7th, 2549: Cortana was created
August 29th, 2552: Cortana met petty officer Master Chief
September 19th, 2552: Master Chief exits cryo-sleep in the Pillar of Autumn (Start of Halo CE)
October 20th, 2552: Master Chief receives the MJOLNIR VI armor. (Start of Halo 2)
November 17th, 2552: Master Chief is found by Johnson and the Arbiter in Africa. (Start of Halo 3)
December 11th, 2552: Master Chief enters cryo-sleep in the Forward Until Dawn.
- At this point, Cortana is 3 years old, 1 month, and 4 days old.
March 3rd, 2553: The ceremony on Earth is held to commemorate those who have fallen in the Human-Covenant War. The Arbiter is present. - At this point, Cortana is 3 years old, 3 month, and 27 days old.
Speculation
Possible Dates of Halo 4:
July 21st, 2557 (When Master Chief goes into Cryo-sleep.)
October 13th, 2557 (When The ceremony on Earth occurs.)
By this time cortana is either 7 years, 8 months, and 14 days old or 7 years, 11 months and 7 days old. (By the time of the ceremony)
I find it interesting that the game takes 4 years, 7 months, and 10 days after Halo 3 because its been about 5 years since Halo 3 came out. Is there a possible correlation with real time, I doubt it, but nonetheless, I find it interesting that they are so closely related.
I hope you guys found this helpful, I just wanted to quickly put the Halo Universe into perspective leading up to the beginning of Halo 4. You see from these dates that the chief and Cortana truly didn’t know each other for that long before coming as close as we saw then in the original trilogy. Now to pose a question; since we have seen that Cortana is way past a normal AI’s life expectancy, how can this affect her in Halo 4 compared to a normal AI. Remember, she may have been altered by the gravemind for all we know that could have given her a longer life span or even a shorter one. It seems that she has a normal state of mind in the first level of Halo 4. (Based on the information GameInformer magazine included.) It claims they have their sarcastic friendly back and forth throughout the first level of the game, so when would we expect Cortana to start dealing with rampancy?
I hope you guys enjoyed this, I worked hard on it
Im excited to see where the Halo Campaign goes!
