## When to prefer this

Use this endpoint when you need to audit, compare, or analyze how South African SARS tax deadlines and filing windows have changed over time, rather than just the current snapshot. Prefer this over the current tax calendar endpoint when historical trending, compliance auditing, or change tracking is required.
