Served 3-day notice to pay or vacate in California on an industrial unit
Hello, when being served with a 3-day notice to pay or vacate, when does the clock start ticking?

Let's say the notice was served and dated today 9/14. Does today count as day 1 or 9/15 count as day 1.

Unit is located in California Riverside County.

Thank you.
