Working Days Calendar

The Working Day Calendar is used to compute the estimated completion date of a contract. To use the calendar, find the start date of the contract, add the working days to the number of the calendar date (a number from 1 to 1000), and subtract 1, find that calculated number in the calendar and that will be the completion date of the contract

NOTE!! Section 4 of the Contract Special Provisions, Beginning of Work, Time of Completion and Liquidated Damages refers to Section 8-1.06, Time of Completion, in the Standard Specifications. That section refers to legal holidays, which are defined in Section 1-1.255 of the Standard Specifications as, " those days designated as State holidays in the Government Code". As of 1997, the government code added Cesar Chavez Day, March 31. All of the printed and on line work day calendars are incorrect if they do not designate March 31 as a non-work day.

NOTE!! As of March 1, 2008, the day after Thanksgiving is considered a nonworking day.
