LHST → PSTGap: -17h 30m1.5h 9-5 overlap

LHST to PST currently uses Lord Howe Time in Australia/Lord_Howe and Pacific Time in America/Los_Angeles as the live reference pair. Right now the gap is -17h 30m, and the sections below break that into meeting-time shortcuts, workday overlap, DST changes, and city coverage on both sides.

Last updated Apr 22, 2026. Offset math, DST behavior, and city coverage on both sides are refreshed from the live timezone dataset during the page revalidation window.

Reverse: PST → LHST

Ambiguity note

PST is ambiguous in this dataset, so the live converter uses America/Los_Angeles as the busiest reference zone while the city list below shows the wider label family.

Pair context

LHST and PST currently connect Australia/Lord_Howe and Los Angeles with a live gap of -17h 30m. Representative coverage on the LHST side is anchored by Australia/Lord_Howe, while the PST side is anchored by Los Angeles, Tijuana, San Diego, and Mexicali.

Using a simple 9:00 AM to 5:00 PM workday on both sides, the pair shares about 1.5 hours of business overlap - roughly LHST 9:00 AM to 10:30 AM, which is PST 3:30 PM previous day to 5:00 PM previous day. The gap is large enough that this pair behaves more like a handoff corridor than a full shared day, which is common for travel plans, follow-the-sun coverage, and async collaboration.

The live gap is -17h 30m right now, based on Australia/Lord_Howe at +10:30 and America/Los_Angeles at -07:00. The zones change on different dates, so there is a DST mismatch window between October 4, 2026 and November 1, 2026. During that stretch the gap shifts to -18h before settling at -19h.

Market coverage on both sides

On the LHST side, the current dataset is anchored by cities such as . That makes this page useful for real-world coordination patterns rather than only abstract offset math.

On the PST side, the live reference set includes Los Angeles, United States; Tijuana, Mexico; San Diego, United States; Mexicali, Mexico; San Jose, United States; San Francisco, United States. In practice, that means the conversion is tied to recognizable business, travel, and support hubs rather than a single anonymous timezone label.

Country usage on the two sides currently includes Australia for LHST and United States, Mexico, and Canada for PST. That country coverage helps explain why some pairs feel like outsourcing, logistics, gaming, finance, or travel-heavy conversions while others are more niche.
