Timezone converter
IST to LHST currently uses India Time in Asia/Kolkata and Lord Howe Time in Australia/Lord_Howe as the live reference pair. Right now the gap is +5h, 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.
IST is ambiguous in this dataset, so the live converter uses Asia/Kolkata as the busiest reference zone while the city list below shows the wider label family.

There is still a usable shared block in the morning or afternoon, so teams can usually meet without pushing too far outside standard hours.
The live gap is +5h right now, based on Asia/Kolkata at +05:30 and Australia/Lord_Howe at +10:30. Australia/Lord_Howe changes offset on October 4, 2026, so the gap moves to +5h 30m after that transition.
On the IST side, the current dataset is anchored by cities such as Mumbai, India; Delhi, India; Bengaluru, India; Hyderabad, India; Ahmedabad, India; Chennai, India. 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 India, Israel, and Sri Lanka for IST 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.
