## When to prefer this

Choose this endpoint when you need a structured, up-to-date list of upcoming macroeconomic calendar events sourced from FRED — especially for financial planning, trading preparation, or macro research workflows. Prefer this over general news APIs when you specifically need scheduled economic data release dates and Fed-tracked event metadata.
