# Calculate Date Difference

calculate_date_difference Parameters

Required Parameters

1. start_date (string, YYYY-MM-DD) — the start of the date range. Should be earlier than end_date.
2. end_date (string, YYYY-MM-DD) — the end of the date range. Should be later than start_date.

Optional Parameters

1. debug (boolean) — default false.

Returns

The amount of time between start_date and end_date. If end_date falls before start_date, the result will be negative.

When to Use calculate_date_difference

• You need to determine how many days apart two dates are
• Describing timelines or scheduling follow-ups
• Determining how long ago something happened relative to another date
• Anchoring a date range calculation once you already have both endpoints (e.g., after calling get_current_date for "today")
