California workers’ compensation deadline calculator

Pick the event that started the clock. Enter the date. Every downstream deadline comes back with its arithmetic shown. Working days are actually counted as working days, and mail extensions are applied only where they belong.

The extension is applied only to periods that run from service of a document, and only where the governing statute does not already build the mailing time in. Each result says which rule it used.

Court closure dates used when counting working days

Working-day counts skip Saturdays, Sundays, and the dates checked here. A holiday falling on a Saturday is treated as observed the Friday before; on a Sunday, the Monday after. Confirm this list against the DIR and DWC published closure calendar for the year you are calculating, and add any local district office closure below.

One date per line or separated by commas, in YYYY-MM-DD format.

Nothing calculated yet.

Choose a triggering event and a date, then select Calculate deadlines. Results appear here in date order with the governing rule beside each one.

This calculator is a drafting aid, not legal advice, and it does not create an attorney-client relationship. Intervals are drawn from the Labor Code, the WCAB Rules of Practice and Procedure, and the Sullivan on Comp treatise sections cited with each result. Statutes, regulations, and court closure calendars change. Verify every date against primary authority and the case file before you rely on it.
