v1.16.11

Fixed

• Day of the Dead now spans November 1–2 in the built-in calendar, matching the decorative overlay's two-day observance.
• Hanukkah appears across all eight calendar days instead of only the first day.
• Rosh Hashanah appears as a two-day observance.
• Ramadan covers the calculated Islamic month (29 or 30 days) instead of only its first day.
• Multi-day holiday events remain visible when they began before the current calendar window, including date ranges crossing month or year boundaries.
• Holiday date arithmetic uses local civil days to avoid one-day shifts around daylight-saving transitions.

Added and Improved

• Passover can be configured as seven days (Israel) or eight days (Diaspora), with eight days as the default built-in setting.
• Holy Week covers seven days from Palm Sunday through Holy Saturday.
• Sukkot covers seven days.
• Eid al-Adha covers four days.
• Kwanzaa spans December 26 through January 1.
• New Year's Eve has its own December 31 calendar entry to match the existing holiday overlay.
• Existing single-day holidays retain their existing single-day durations.
• Built-in holiday options remain individually controllable, and optional holiday add-ons remain disabled by default.
