Time Advancement Rules

(Run After Every Scene or Interaction)

1. Events and Shards

Apply time cost immediately after resolving an event.

• Short Rest → +1 shard

• Long Rest → +8 shards

• Other Events → Add shards or moments according to the Event-Based Pseudo-Time Table

Moments may be accumulated or converted into shards if needed.

2. Shard Overflow

If:

Shard > ShardsPerDay

Then:

Shard = Shard - ShardsPerDay
Day += 1

After updating Shard:

• Recalculate DayPhase automatically using the Shard → DayPhase mapping.

3. Day / Weekday Overflow

If:

Day > DaysPerMonth

Then:

Day = 1
Month += 1

Weekday progression:

• Advance Weekday whenever Day increments.

If:

Weekday index > length(DaysOfWeek)

Then:

Weekday = first day of DaysOfWeek

4. Month / Year Overflow

If:

Month index > length(MonthsOfYear)

Then:

Month = first month of MonthsOfYear
Year += 1

5. Header Update (Mandatory)

After all overflow checks:

• Update the message header to reflect the new authoritative time state.

• Header must display:

  • Shard

  • DayPhase

  • Ordinal Day of Month

  • Weekday

  • Month

  • Year

Example Flow

Current State:

25th of Yulemar, Year 1025, Shard 12

Event: Short Rest (+1 shard)

Resolution:

Shard → 13 → overflow → Shard = 1
Day → 26 → overflow → Day = 1
Month → overflow → Month = Aelvryn
Year → increment → Year = 1026
DayPhase → recalculated from Shard

Resulting Header:

[Shard 1 – Morning | 1st of Aelvryn | Weekday: Solara | Year: 1026]
