Court Day Calculator: Count Real Business Days, Not Just Calendar Squares
Set your filing date, add the holidays your court actually observes, and get a deadline that reflects real courthouse-open days, not a rough guess.
The date your deadline period begins, such as the date of service or an order.
If your court's rules add extra days for mailed or electronic service, enter that number here. Check your specific code section or court rule, since this figure varies and this tool does not assume one for you.
A starter list of common US federal holidays is included. Add, remove, or edit dates to match your court's actual published calendar for the relevant year.
Day-by-day count
Why Court Days Almost Never Match a Simple Calendar Count
Tell someone their deadline is five court days away and they might mentally flip five squares on a calendar and call it done, but that shortcut breaks the moment a weekend or holiday sits inside that window. Courts don't operate on weekends, and they close for a recognized list of holidays each year, both of which get skipped entirely when a rule is written in court days rather than calendar days. That's the entire reason this calculator exists, to walk through real open days one at a time instead of assuming every square on a calendar counts equally.
Why the Holiday List Is Editable Instead of Fixed
A hardcoded holiday list sounds convenient until it's wrong for your specific year or your specific court, and being wrong about a filing deadline is exactly the kind of mistake nobody can afford. Court closure calendars shift slightly year to year, and different courthouses within the same state don't always observe identical closure days. Rather than quietly guessing on your behalf, this tool starts you off with a common baseline of US federal holidays and lets you add, edit, or remove any date so the count matches your court's actual published calendar.
Handling Service Extensions the Honest Way
Plenty of procedural rules add extra time to a deadline depending on how a document was served, mailed, emailed, or handed over in person, and the exact number of added days is set by specific code sections that vary by jurisdiction and sometimes by case type. Rather than baking in a number that might be right for one situation and wrong for another, this calculator simply gives you a field to enter whatever extension applies to your case once you've confirmed it, keeping the tool accurate instead of quietly confident about something it can't actually know.
Reading Your Day-by-Day Count
The table beneath your result walks through every single day between your start date and deadline, marking which ones counted toward your total and which were skipped as a weekend or holiday. This isn't just for show, having a clear, checkable record of exactly how a deadline was reached is genuinely useful if that date ever gets questioned later.
Beyond Los Angeles: Using This for Any Court System
While plenty of people search for this tool specifically around LASC filings, the underlying mechanics, weekday counting with a skippable holiday list, apply just as well to any other court, whether that's a different California county, another state entirely, or a federal court. Just swap in the correct holiday calendar and counting rules for your specific jurisdiction and the math works the same way everywhere.

Frequently Asked Questions
What is a court day and how is it different from a calendar day?
A court day is a day the courthouse is actually open, excluding weekends and official holidays, while a calendar day counts every day regardless. Deadlines written in court days are usually longer in real time than the same number of calendar days.
Does mailing a document add extra days to my deadline?
Often yes, but the exact number varies by jurisdiction and rule, so this calculator lets you enter your own confirmed extension rather than assuming a fixed figure.
Are LASC court holidays the same every year?
Mostly, but closures can shift or be added for a specific year, so always check your court's official current holiday calendar rather than relying on memory or an old list.
Can I use this calculator for courts outside Los Angeles?
Yes, since the holiday list and counting rules are fully editable, it works for any court system as long as you enter the correct details for your specific jurisdiction.
