Discovery Response Deadline Calculator

Estimate a discovery response due date from the service date, response period, service add-on days, and optional manual deadline override.

Date served or received

Use the date the discovery request was served, delivered, or received.

Response period in days

Type any custom number your rule allows. Common choices include 20, 30, 33, 35, or 45 days.

Extra service days

Use 0 if no extra time applies, or type your own custom add-on days.

Manual final deadline Optional

Use this only when a court order, stipulation, or local rule gives a specific date. It will show as the final deadline while still displaying the calculated rule deadline.

Counting method

Calendar days are common, but some local rules or orders may require business days.

Court holidays to skip Optional

Enter holiday dates as YYYY-MM-DD, separated by commas, spaces, or new lines.
