skuddårreflect

Skuddårreflect is a conceptual framework used in calendrical computation and software design to model the effect of leap years on date arithmetic. The name combines skuddår, the Scandinavian term for leap year, with reflect, signaling a treatment that makes leap-year behavior explicit in data models.

The central idea of skuddårreflect is to treat leap day not as a single exception in code, but as an integral axis of time representation. It aims to provide precise handling of February 29 across long time horizons, ensure consistency between different calendar systems, and facilitate simulations that test calendar-related logic under extended date ranges.

Typical implementations would include rules for detecting leap years under the proleptic Gregorian calendar, support for alternate calendars, and clear specification of how to map dates to continuous time scales. It also emphasizes explicit handling of edge cases around locale and time zone transitions to avoid drift in scheduling and analytics.

Skuddårreflect is primarily discussed in theoretical discussions on calendar systems and in the design of robust date-time libraries. It is not a formal standard, but a concept that informs best practices for leap-year-aware software. Related topics include leap year rules, ISO 8601, Proleptic Gregorian calendar, and calendar arithmetic.
