Fórmula y Método de Cálculo
Fecha de destino = Fecha de anclaje ± [Años, Meses, Días]
Because months have variable lengths (28, 29, 30, 31), adding '1 Month' to January 31st mathematically defaults to February 28th (or 29th), requiring complex boundary-handling algorithms within the JS engine.
Mejores Prácticas y Consejos
- Understand Inclusive vs Exclusive Boundaries: If a hotel is booked for '3 nights' starting Friday, the checkout is Monday. The calculation must exclude the final day from the count to represent physical overnight stays accurately.
- Use for Software Sprints: Agile engineering teams rely on strict 14 day intervals (Sprints). Using a date calculator ensures all Jira ticket deadlines and retrospective meetings align perfectly with the calendar matrix.
- Watch for Timezone Bleed: When manipulating raw date objects in JavaScript, the browser will attempt to apply the user's local timezone. Always force calculations into absolute UTC to prevent dates from shifting by ±1 day.
