The Mars Century timeline, or MC for short, is a continuation of the After Colony timeline of Mobile Suit Gundam Wing and its follow-up Mobile Suit Gundam Wing: Endless Waltz in which the events of the novel New Mobile Report Gundam Wing: Frozen Teardrop take place.
Due to the difference in measuring passing time between Mars and Earth (1 Mars year = about 2 Earth years), events are measured using Mars years and Earth seasons- i.e. MC-0022 First Winter (First winter season, Earth years) vs MC-0022 Next Winter (The next year's Winter, Earth years).
