What UTC and EDT Actually Are

UTC — Coordinated Universal Time

The global reference standard. Aviation, computing and science run on it. Standing at UTC as written, and the region does not change its clocks, so that offset holds all year.

UTC is not a place. It is a computed standard, kept within a second of mean solar time at Greenwich by atomic clocks, and it is the reference every other zone is defined against.

EDT — Eastern Daylight Time

New York, Toronto, Washington DC, Atlanta, Miami, Boston. Standing at UTC-4:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to EST.

EDT runs from the second Sunday in March to the first Sunday in November — about eight months, making the "daylight" version the majority of the year rather than the exception.

What This Means in Practice

This gap is not fixed

EDT changes its clocks and UTC does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.
