Timezone converter
TMT to IST currently uses Turkmenistan Time in Asia/Ashgabat and India Time in Asia/Kolkata as the live reference pair, with a +0h 30m live gap. TMT to IST matters whenever Ashgabat and Mumbai need to coordinate across a +0h 30m gap. The TMT side covers Turkmenistan, while IST covers India and Israel — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
Last updated Apr 30, 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.

Based on the busiest city and zone usage found in the current dataset.
TMT (Ashgabat, +05:00) to IST (Mumbai, +05:30) is currently a +0h 30m conversion. Live coverage on the TMT side is anchored by Ashgabat, Türkmenabat, Daşoguz, and Mary; the IST side draws from Mumbai, Delhi, Bengaluru, and Hyderabad.
TMT to IST matters whenever Ashgabat and Mumbai need to coordinate across a +0h 30m gap. The TMT side covers Turkmenistan, while IST covers India and Israel — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
Both reference zones sit inside Asia, so this is a regional comparison rather than a long-haul conversion. The gap of +0h 30m mostly affects intra-continental travel, regional logistics, and Asia-wide calendars.
Neither TMT nor IST observes daylight saving on the reference zones used here, so the gap stays steady all year. That makes this pair predictable for recurring meetings, broadcast schedules, and contracts that care about a stable offset.
TMT and IST sit 0h 30m apart, leaving a generous 7.5h 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.
TMT coverage on this page is led by Ashgabat, Turkmenistan, Türkmenabat, Turkmenistan, Daşoguz, Turkmenistan, and Mary, Turkmenistan, with 2 more in the live dataset. That mix is what makes TMT feel anchored to South and Southeast Asian business hubs in practice rather than just an abbreviation on a chart.
IST coverage is led by Mumbai, India, Delhi, India, Bengaluru, India, and Hyderabad, India, with 2 more anchoring the wider label family. Combined with the TMT side, this conversion ends up describing intra-Asia regional logistics and travel coordination.
