Do I count number of hours worked in a state or times entered a state to get number of days when worked in another state from where I lived?

Where are you encountering this question? You are a resident of OR and a non-resident of CA.

Is the question due to the following information from CA?

G Guidelines for Determining Residency

The underlying theory of residency is that you are a resident of the place where you have the closest connections. The following list shows some of the factors you can use to help determine your residency status. Since your residence is usually the place where you have the closest ties, you should compare your ties to California with your ties elsewhere. In using these factors, it is the strength of your ties, not just the number of ties, that determines your residency. This is only a partial list of the factors to consider.

No one factor is determinative. Consider all the facts of your particular situation to determine your residency status.

Factors to consider are as follows:

• Amount of time you spend in California versus the amount of time you spend outside California.

Simple answer: count hours.

You  allocate the portion of your salary earned in CA.  If your employer does not do that for you on your W-2, you use the most reasonable method.  Since you apparently don't spent the full day working in CA, hours would be most reasonable.
