Update holiday year

Updates the validity period (validTill) of a custom holiday year configuration.

What this does: Changes how long a custom holiday configuration applies to future years. This is useful when you want to extend or limit the scope of your customizations.

How validTill works:

• Set to a specific year (e.g., 2026): The configuration applies from the year’s start year through 2026

  • Future years within this range will be automatically created as “derived” configurations
  • Years beyond validTill will use default holidays

• Set to null: The configuration applies indefinitely to all future years

  • All future years will automatically inherit this configuration as “derived” years
  • Useful for permanent company holidays that should always apply

Example scenarios:

1. Temporary change: You add a special holiday for 2024-2025 only

   • Create year 2024 with validTill: 2025
   • Both 2024 and 2025 will use the custom configuration
   • 2026 and beyond will use defaults

2. Permanent company holiday: You add “Company Foundation Day” that should always be a holiday

   • Create year 2024 with validTill: null
   • All future years will automatically include this holiday

3. Extending validity: You previously set validTill: 2025 but want to extend to 2027

   • Update the year with validTill: 2027
   • Years 2026 and 2027 will now also use the custom configuration

Note: This endpoint only works on custom holiday years (those with an id). Default years cannot be updated - you must create a custom year first using POST /holidays/years.
