Conversor de EST para WEST.

EST → WESTGap: +5h3h 9-5 overlap

EST to WEST currently uses Eastern Time in America/New_York and Western European Time in Africa/Casablanca as the live reference pair, with a +5h live gap. EST to WEST matters whenever New York City and Casablanca need to coordinate across a +5h gap. The EST side covers United States and Canada, while WEST covers Morocco and Portugal — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.

Last updated Apr 26, 2026. Offset math, DST behavior, and city coverage on both sides are refreshed from the live timezone dataset during the page revalidation window.

How this is calculated

How we calculate this
The current offset for each abbreviation is resolved against the live IANA timezone rules. Conversion accounts for DST transitions on both sides, so the gap between EST and WEST can change by an hour twice a year.

Pair context

EST (New York City, -04:00) to WEST (Casablanca, +01:00) is currently a +5h conversion. Live coverage on the EST side is anchored by New York City, Toronto, Brooklyn, and Queens; the WEST side draws from Casablanca, Rabat, Fes, and Tangier.

EST to WEST matters whenever New York City and Casablanca need to coordinate across a +5h gap. The EST side covers United States and Canada, while WEST covers Morocco and Portugal — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.

This pair crosses the Atlantic, with one side in the Americas and the other in Europe or Africa. The +5h gap is small enough that there is still a real shared midday window, which is why transatlantic finance, broadcasting, and conference scheduling lean on this conversion.

Both EST (America/New_York) and WEST (Africa/Casablanca) 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.

EST and WEST sit exactly 5h apart, with about 3h of shared 9-to-5 time. That is enough room for one daily standup plus one focused working session, which is what most cross-region teams actually use this overlap for.

Market coverage on both sides

EST coverage on this page is led by New York City, United States, Toronto, Canada, Brooklyn, United States, and Queens, United States, with 2 more in the live dataset. That mix is what makes EST feel anchored to East Coast and Central American business activity in practice rather than just an abbreviation on a chart.

WEST coverage is led by Casablanca, Morocco, Rabat, Morocco, Fes, Morocco, and Tangier, Morocco, with 2 more anchoring the wider label family. Combined with the EST side, this conversion ends up describing transatlantic finance, broadcast scheduling, and same-day cross-border product launches.

Operational notes

EST to WEST ranges from EST 9:00 AM (which lands at WEST 2:00 PM) through EST 9:00 PM (WEST 2:00 AM). Across this +5h gap, the middle of the EST range usually lands in the WEST afternoon — the reliable window for live calls between the two — while the early and late edges drift into WEST morning or evening.

Overlap window and DST radar

The live gap is +5h right now, based on America/New_York at -04:00 and Africa/Casablanca at +01:00. The zones change on different dates, so there is a DST mismatch window between November 1, 2026 and February 7, 2027. During that stretch the gap shifts to +6h before settling at +5h.

The most usable workday block right now is about 3 hours: EST 9:00 AM previous day to 12:00 PM previous day, which lines up with WEST 2:00 PM previous day to 5:00 PM previous day.

America/New_York changes on November 1, 2026 at about 1:14 AM, moving from -05:00 to -05:00.
Africa/Casablanca changes on February 7, 2027 at about 2:29 AM, moving from +00:00 to +00:00.
