5:00 pm PT might be unsuitable for EDT time zone
When planning a call between Pacific Time and Eastern Daylight Time, you need to consider time difference between these time zones. PT is 3 hours behind of EDT.
It is 5:00 pm in PT. This does not fall within the span of usual working time between 12:00 pm and 6:00 pm in EDT, but it still might be suitable to arrange a meeting, since it would be 8:00 pm in EDT, which is between 7:00 am and 11:00 pm EDT time.
