PST → MDTGap: +1h7h 9-5 overlap

PST to MDT currently uses Pitcairn Time in America/Los_Angeles and Mountain Time in America/Ciudad_Juarez as the live reference pair, with a +1h live gap. PST to MDT matters whenever Los Angeles and Ciudad Juárez need to coordinate across a +1h gap. The PST side covers United States and Mexico, while MDT covers Mexico and Canada — 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 PST and MDT can change by an hour twice a year.

Pair context

PST (Los Angeles, -07:00) to MDT (Ciudad Juárez, -06:00) is currently a +1h conversion. Live coverage on the PST side is anchored by Los Angeles, Tijuana, San Diego, and Mexicali; the MDT side draws from Ciudad Juárez, Calgary, Edmonton, and Denver.

PST to MDT matters whenever Los Angeles and Ciudad Juárez need to coordinate across a +1h gap. The PST side covers United States and Mexico, while MDT covers Mexico 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 +1h mostly affects intra-continental travel, regional logistics, and America-wide calendars.

Both PST (America/Los_Angeles) and MDT (America/Ciudad_Juarez) 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.

PST and MDT sit exactly 1h apart, leaving a generous 7h 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.

Market coverage on both sides

PST coverage on this page is led by Los Angeles, United States, Tijuana, Mexico, San Diego, United States, and Mexicali, Mexico, with 2 more in the live dataset. That mix is what makes PST feel anchored to West Coast and Pacific-edge American activity in practice rather than just an abbreviation on a chart.

MDT coverage is led by Ciudad Juárez, Mexico, Calgary, Canada, Edmonton, Canada, and Denver, United States, with 2 more anchoring the wider label family. Combined with the PST side, this conversion ends up describing intra-America regional logistics and travel coordination.
