kiloversary 

Kiloversary or k-day refers to the day when someone or something is an even multiple of 1000 days old. Such as: when someone is 35 years, 7 months and 3 days old they can celebrate their 13th kiloversary or k-day.

I used WolframAlpha to figure out what my kiloversary is.

Kardashev Type 9.0 Kiloversal Civilizations

A civilization whose domain is a "kiloverse"—a vast, but perhaps not infinite, collection of thousands (kilo-) of distinct hyperverses or equivalent cosmic structures. This represents a scale of organization so vast that the concept of "individual universe" is as meaningless as a single atom is to us. Their engineering projects might involve balancing the cosmological constants across entire ensembles of reality-stacks.

Kardashev Type 9.0 Kiloversal Civilizations Example: There is little direct fiction for this, but it would be akin to the Anti-Monitor from DC Comics at his fullest power, threatening not just one universe but the entire infinite Multiverse, or a being that exists as the administrator for a vast, but finite, array of simulated omniverses.
