The 世代暦 Sedaireki is a fictional calendar (based on the old Japanese calendar) to track the cycles of years. Instead of a 1-to-1 day system, the timeframe is condensed so that characters age and pass on for new generations to take their place.
| Our Time | Game Time | Details |
|---|---|---|
| 1 Day | １節気 Sekki | The 24 divisions of the year. These terms mark the changing of seasons in Japan. |
| 1 Week | １季節 Kisetsu | The four seasons (春夏秋冬). Each season has 6 Sekki. The 7th day of each week is skipped. |
| ‹1 Month (28 days) | １代 Dai | The zodiac year, each of the 12 years named for an animal of the Chinese zodiac. For the time scale, one Dai actually equals about a decade of a character's lifetime. |
| ‹1 Year (336 days) | １世 Sei | The cycle of all 12 zodiac years. A character's life lasts about half of a cycle; much like a century. |
Proper notation of the date follows: ○世○代節気
○世：零世、壱世、弐世、參世、四世、伍世、…（0,1,2,3,4,5,…）
