GMT → LHSTGap: +9h 30mNo 9-5 overlap

GMT to LHST currently uses Greenwich Mean Time in Europe/London and Lord Howe Time in Australia/Lord_Howe as the live reference pair. Right now the gap is +9h 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: LHST → GMT

Ambiguity note

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

Pair context

GMT and LHST currently connect London and Australia/Lord_Howe with a live gap of +9h 30m. Representative coverage on the GMT side is anchored by London, Abidjan, Bamako, and Dakar, while the LHST side is anchored by Australia/Lord_Howe.

Using a simple 9:00 AM to 5:00 PM workday on both sides, this pair has no strict overlap right now. Meetings usually work best as early-late handoffs rather than midday sessions. 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 +9h 30m right now, based on Europe/London at +01:00 and Australia/Lord_Howe at +10:30. The zones change on different dates, so there is a DST mismatch window between October 4, 2026 and October 25, 2026. During that stretch the gap shifts to +10h before settling at +11h.

Market coverage on both sides

On the GMT side, the current dataset is anchored by cities such as London, United Kingdom; Abidjan, Ivory Coast; Bamako, Mali; Dakar, Senegal; Kumasi, Ghana; Ouagadougou, Burkina Faso. That makes this page useful for real-world coordination patterns rather than only abstract offset math.

On the LHST side, the live reference set includes . 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 United Kingdom, Ivory Coast, and Mali for GMT and Australia for LHST. That country coverage helps explain why some pairs feel like outsourcing, logistics, gaming, finance, or travel-heavy conversions while others are more niche.

Operational notes

GMT to LHST meeting times is easiest to read as a working-day range rather than a single spot conversion. In the current snapshot, 9:00 AM lands at 6:30 PM, while 9:00 PM lands at 6:30 AM, which makes the practical handoff window much easier to scan.

Overlap window and DST radar

The live gap is +9h 30m right now, based on Europe/London at +01:00 and Australia/Lord_Howe at +10:30. The zones change on different dates, so there is a DST mismatch window between October 4, 2026 and October 25, 2026. During that stretch the gap shifts to +10h before settling at +11h.

There is no strict 9 AM to 5 PM overlap right now, so this pair is better for handoffs, travel planning, or async coordination than for midday meetings.

Australia/Lord_Howe changes on October 4, 2026 at about 2:39 AM, moving from +11:00 to +11:00.
Europe/London changes on October 25, 2026 at about 1:24 AM, moving from +00:00 to +00:00.
