Do we have to change memory to match the calendar
7800The deep futureDeadline · Within 60 years, before the new communication cycle
Civilisational assumption
The people, events, figures, and contract terms are a synthetic premise. They are not statements of real cases or of current law. The source documents are the roots of the background and the norms and do not establish the premises of the scenario.
The question to decide
A single calendar reduces exchange errors, but one civilization would have to restructure its memory and its rites. Keeping each standard means depending on conversion bodies and bearing the errors. Taking even the option of simply numbering shared events into account, what burden should be accepted to align the time that exchange requires?

The options
The order shown is not a ranking of preference.
The situation as it stands
Each civilization has different recurring environmental cycles and different ways of distinguishing memories, and the same date does not mean the same interval. Decision deadline: within 60 years, by the new communication cycle.
Synthetic scenario set in the year 7800 · Changing the common calendar breaks the order of one civilization's memory. The events, figures, technologies, and nature of the civilizations are assumptions for the question, not predictions of what is to come or observed facts.
- Premise 1Each civilization has different recurring environmental cycles and different ways of distinguishing memories, and the same date does not mean the same interval.
- Premise 2A single calendar can reduce exchange errors, but one civilization would have to reclassify its own memories.
- Premise 3Multiple conversions require translation bodies that must be maintained, and an omission can change the committed deadlines.

What is still unknown
- Unknown 1The operational moments that actually have to align
- Unknown 2Errors in time conversion and the authority to correct them
- Unknown 3The scope of experience that a calendar change cannot be undone for
Signals to decide again
- Decide what observation, responsible person, and confirmation window can verify 「the operational moments that actually have to align」, and render a fresh judgment if the new verification changes the trade-offs of the options.

Where the paths partNot answers — paths that part from the same starting point
One converted deadline was read in the two civilizations as the responsibility of two different generations.
A pilot run showed that essential operations of a shared facility can be met even with a sequence-number method.

An exploratory perspective chosen by the creator. Does not claim supernatural validity or the superiority of any particular option.The benefits and costs of the options accrue to different stakeholders. Which loss to accept remains undecided.
