Quick answer
8 AM PDT is 4 PM BST in London during summer. Pacific Daylight Time (UTC-7) and British Summer Time (UTC+1) are 8 hours apart. This is one of the best Pacific-to-London slots for live meetings.
How to use this time conversion
8 AM Pacific Daylight Time is the summer equivalent of 8 AM PST in winter. Both map to the same London time 鈥?4 PM 鈥?because both the US West Coast and the UK shift forward by one hour in spring, keeping the gap at 8 hours. PDT runs from mid-March to early November; BST runs from late March to late October. For the brief transition weeks in spring and autumn when one zone has changed clocks and the other has not, the gap temporarily shifts to 7 or 9 hours 鈥?always verify for calls around those dates.
For one-time calls, confirm the exact date before sending the invite. For recurring calls, use the Meeting Time Finder to verify the overlap stays inside working hours after every daylight saving change.
What is 8 AM PDT in London?
8 AM PDT is 4 PM BST in London during summer. PDT (UTC-7) and BST (UTC+1) are 8 hours apart. This is the same result as 8 AM PST in winter (4 PM GMT), since both zones shift clocks in spring.
How is PDT different from PST for London calls?
PDT (Pacific Daylight Time, UTC-7) applies from mid-March to early November. PST (Pacific Standard Time, UTC-8) applies the rest of the year. Because the UK also shifts to BST in summer, London stays 8 hours ahead of Pacific time all year 鈥?making the conversion the same in both seasons.
Are there weeks when 8 AM PDT gives a different London time?
Yes 鈥?during the transition weeks when one zone switches and the other has not yet. This typically happens in late March (US switches before UK) and late October (UK switches before US). During those short windows, the gap is temporarily 7 or 9 hours. Always check the tool for exact dates near the transitions.
Can I use this conversion for all summer meetings?
Yes, 8 AM PDT = 4 PM BST holds from approximately late March to late October. Use the Meeting Time Finder to confirm for any specific date, especially around the transition weeks.
