Court Date Calculators by Jurisdiction

Use these court date calculators to estimate filing deadlines, response dates, and hearing-related due dates for specific court systems. Each calculator shows the calculation process so you can review how the date was estimated.

LASC Court Date Calculator

For Los Angeles Superior Court and LA County court deadline estimates.

California Court Date Calculator

For California state court deadline estimates and statewide court resources.

Federal Court Date Calculator

For federal civil deadline estimates based on Federal Rule of Civil Procedure 6.

General Court Date Calculator

Need a general court date calculator that is not specific to a jurisdiction? Use the general Court Date Calculator on the home page to estimate deadlines with calendar-day or business-day counting and weekend/holiday adjustment.

Choose the Calculator That Matches Your Source Rule

General calculator

Use this when you already know the start date, number of days, direction, counting method, and weekend or holiday treatment required by the rule.

California and LASC calculators

Use these to organize a California or Los Angeles deadline estimate and reach official court resources. Confirm whether statewide rules, local rules, or a judge's order control.

Federal calculator

Use this for estimates based on Federal Rule of Civil Procedure 6. The substantive rule that creates the deadline still determines the length and triggering event.

Before You Calculate

  1. Find the rule that creates the deadline. A calculator cannot decide which statute, procedural rule, local rule, standing order, or scheduling order applies.
  2. Identify the triggering event. Filing, entry of an order, service, notice, a hearing, or another event may start the period. Use the event stated in the controlling text.
  3. Confirm how days are counted. Check whether the first day is excluded, whether every calendar day is counted, and how weekends and legal holidays affect the last day.
  4. Check service rules separately. Do not add extra days for mail or electronic service unless the current rule expressly allows it.
  5. Review the displayed breakdown. Compare the estimated date and each adjustment against the source rule before relying on the result.

What These Calculators Do Not Determine

The tools do not determine jurisdiction, select a legal rule, interpret an order, calculate limitation periods from disputed facts, or guarantee that a filing will be accepted. Emergency procedures, sealed matters, criminal cases, administrative proceedings, and individual judge practices may use rules not represented by a general date calculator.

For a real case, keep a copy of the source rule and the calculation inputs with your file. If the date is important or uncertain, verify it through official court materials and a qualified attorney. You can also review our Editorial Policy to understand how we source and update legal information.

These calculators provide general date estimates only and do not provide legal advice. Court rules, local rules, case type, court orders, filing method, and holidays may change a deadline. Always verify the result with the applicable court rules or a qualified attorney before relying on it.
