6:00 am PST might be unsuitable for PDT time zone
When planning a call between Pacific Standard Time and Pacific Daylight Time, you need to consider time difference between these time zones. PST is 1 hour behind of PDT.
It is 6:00 am in PST. This does not fall within the span of usual working time between 10:00 am and 6:00 pm in PDT, but it still might be suitable to arrange a meeting, since it would be 7:00 am in PDT, which is between 7:00 am and 11:00 pm PDT time.
