Timezone converter
IST to TMT currently uses India Time in Asia/Kolkata and Turkmenistan Time in Asia/Ashgabat as the live reference pair, with a -0h 30m live gap. IST to TMT matters whenever Mumbai and Ashgabat need to coordinate across a -0h 30m gap. The IST side covers India and Israel, while TMT covers Turkmenistan — 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.
IST (Mumbai, +05:30) to TMT (Ashgabat, +05:00) is currently a -0h 30m conversion. Live coverage on the IST side is anchored by Mumbai, Delhi, Bengaluru, and Hyderabad; the TMT side draws from Ashgabat, Türkmenabat, Daşoguz, and Mary.
IST to TMT matters whenever Mumbai and Ashgabat need to coordinate across a -0h 30m gap. The IST side covers India and Israel, while TMT covers Turkmenistan — 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 IST nor TMT 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.
IST and TMT 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.
IST coverage on this page is led by Mumbai, India, Delhi, India, Bengaluru, India, and Hyderabad, India, with 2 more in the live dataset. That mix is what makes IST feel anchored to South and Southeast Asian business hubs in practice rather than just an abbreviation on a chart.
TMT coverage is led by Ashgabat, Turkmenistan, Türkmenabat, Turkmenistan, Daşoguz, Turkmenistan, and Mary, Turkmenistan, with 2 more anchoring the wider label family. Combined with the IST side, this conversion ends up describing intra-Asia regional logistics and travel coordination.
