Description

Is your feature request related to a problem? Please describe.
The maxCalendarYear for Schedules is currently hardcoded to 2100.

  • This prevents users from scheduling workflows or timers that need to extend beyond that year, which can be a blocker for long-running or far-future scheduling use cases.
  • or are expected to update Schedules once this limit is increased

Describe the solution you'd like
Either increase the default maxCalendarYear limit, or make it configurable via DynamicConfig so that operators can adjust it without requiring a code change or redeployment.

Describe alternatives you've considered

Additional context

  • this was a question from customer for payments
