* **Pacific Standard Time (PST / UTC-8):** In effect from the first Sunday in November to the second Sunday in March. During this period, Hong Kong is 16 hours ahead of the Pacific Time zone. * **Pacific Daylight Time (PDT / UTC-7):** In effect from the second Sunday in March to the first Sunday in November. During this period, Hong Kong is 15 hours ahead of the Pacific Time zone. Because of this shift, a 7:00 AM HKT call will map to two different times in the Pacific Time zone depending on the season: * **During PST (Winter):** 7:00 AM HKT (e.g., Tuesday) = 3:00 PM PST (e.g., Monday) * **During PDT (Summer):** 7:00 AM HKT (e.g., Tuesday) = 4:00 PM PDT (e.g., Monday) ## Step-by-Step Guide to Scheduling the Call
Follow these steps to ensure your meeting is scheduled accurately for participants in both regions. ### 1. Verify the Date and Day of the Week Because HKT is 15 to 16 hours ahead of Pacific Time, a morning call in Hong Kong always takes place on the calendar day after the afternoon call in the US. If you want to speak on a Tuesday morning in Hong Kong, the US participant must join the call on Monday afternoon. Always explicitly state both dates and days of the week in your communications to prevent confusion. ### 2. Confirm the US Daylight Saving Status Before sending the invitation, confirm whether the US is currently observing PST or PDT. This determines whether the call will take place at 3:00 PM or 4:00 PM Pacific Time. ### 3. Send a Dual-Time Calendar Invite When sending the calendar invitation, include both time zones in the subject line or description. For example: * "Project Sync: Tuesday 7:00 AM HKT / Monday 3:00 PM PST"
Using digital calendar platforms is highly recommended. Sending an invite through standard calendar applications will automatically convert the meeting time to the recipient's local time zone, reducing the risk of manual calculation errors. ## Key Challenges and How to Overcome Them While the 7:00 AM HKT window is highly functional, it does present a few operational challenges. * **End-of-Day vs. Start-of-Day Energy:** The US participant is finishing their workday, while the Hong Kong participant is just starting theirs. Keep meetings focused and action-oriented to accommodate these differing energy levels. * **The Monday/Sunday Conflict:** A Monday morning call in Hong Kong (7:00 AM HKT) requires the US participant to work on Sunday afternoon (3:00 PM or 4:00 PM Pacific Time). To respect the weekend, it is best to schedule these calls Tuesday through Friday HKT, which corresponds to Monday through Thursday Pacific Time.
## Alternative Meeting Windows If 7:00 AM HKT does not work for all parties, finding another overlap during standard working hours can be difficult. For instance, scheduling a call during the US morning (e.g., 9:00 AM PST) translates to 1:00 AM HKT (or 2:00 AM HKT during Standard Time). Similarly, scheduling a call during the Hong Kong afternoon (e.g., 3:00 PM HKT) translates to 11:00 PM or 12:00 AM Pacific Time. Consequently, the 7:00 AM HKT (3:00 PM / 4:00 PM Pacific Time) window remains the most practical option for standard business hours, as it avoids forcing either party to take calls in the middle of the night.
