PDTからESTへの変換.

PDT (Los Angeles, -07:00) to EST (New York City, -04:00) is currently a +3h conversion. Live coverage on the PDT side is anchored by Los Angeles, Tijuana, San Diego, and Mexicali; the EST side draws from New York City, Toronto, Brooklyn, and Queens.

PDT to EST matters whenever Los Angeles and New York City need to coordinate across a +3h gap. The PDT side covers United States and Mexico, while EST covers United States and Canada — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.

Both reference zones sit inside America, so this is a regional comparison rather than a long-haul conversion. The gap of +3h mostly affects intra-continental travel, regional logistics, and America-wide calendars.

Both PDT (America/Los_Angeles) and EST (America/New_York) observe daylight saving, but the shift dates do not always align. Expect short mismatch windows in spring and autumn when one side has changed and the other has not, which moves the live gap by an hour for several weeks at a time.

PDT and EST sit exactly 3h apart, leaving a generous 5h of shared 9-to-5 time. With that much overlap, this pair behaves almost like a single workday, so meeting times are negotiable rather than forced into a narrow corner of the calendar.
