SAST ↔ IST Time Converter

India Standard Time (IST) is 3h 30m ahead of South Africa Standard Time (SAST). SAST runs at UTC+2 and IST at UTC+5:30. Quick time examples: 8:00 AM SAST = 11:30 AM IST; 12:00 PM SAST = 3:30 PM IST; 5:00 PM SAST = 8:30 PM IST.

To convert SAST to IST, add 3 hours 30 minutes to the SAST time. For example, 12:00 PM SAST becomes 3:30 PM IST. When the result crosses midnight, advance the date by one day (shown as "+1 Day" in the converter). Because IST uses a :30 offset, results always land on a :30-minute mark.

India Standard Time (IST) is 3h 30m ahead of South Africa Standard Time (SAST). Reversed: SAST is 3h 30m behind of IST. Practical example: noon in New Delhi (12:00 PM IST) corresponds to 8:30 AM SAST in Johannesburg, and 5 PM in New Delhi corresponds to 1:30 PM SAST.

South Africa Standard Time (SAST) is the standard civil time for Johannesburg and the surrounding region, operating at UTC+2 from UTC. It does not observe Daylight Saving Time; the UTC offset stays at UTC+2 every day of the year. Major cities: Johannesburg, Cape Town, Durban, Pretoria, Port Elizabeth, Bloemfontein, East London.

India Standard Time (IST) covers New Delhi and the surrounding region at UTC+5:30 from UTC. It does not observe Daylight Saving Time — the offset is fixed at UTC+5:30 all year with no seasonal change. Cities in this zone: New Delhi, Mumbai, Bangalore, Chennai, Kolkata, Hyderabad, Colombo.

No — and this makes SAST–IST one of the simpler pairs to schedule across. Neither zone observes Daylight Saving Time, so the offset is exactly 3h 30m ahead every single day of the year. You can set up a recurring calendar invite once and never adjust it for seasonal clock changes on either side.

The best meeting window is where standard working hours (9 AM – 6 PM) overlap in both zones. Since IST is 3h 30m ahead of SAST, mornings in the earlier zone align with afternoons or evenings in the later zone. Target 8 AM – 11 AM in the earlier-offset zone to keep both sides in reasonable hours. The meeting hours table above shows the exact recommended slots for this pair. Any time where one side falls before 7 AM or after 9 PM is best avoided for regular team calls.

Type any time directly into the IST field in the bidirectional converter above — it instantly shows the SAST result. Alternatively, subtract 3 hours 30 minutes from the IST time manually. For a dedicated reverse page, visit: IST to SAST converter ↗.

For some hours of the day the conversion does cross midnight into the next or previous calendar day. When the converted time passes 11:59 PM, the date advances — the converter shows "+1 Day". When it goes before 12:00 AM, the date moves back — "-1 Day" appears. The 24-hour reference table also shows day changes in the Day column. Always check the date indicator when sending calendar invites across these two zones to avoid accidentally booking on the wrong date.

South Africa Standard Time (SAST) is used in: Johannesburg, Cape Town, Durban, Pretoria, Port Elizabeth, Bloemfontein, East London. The zone operates at UTC+2, with a constant offset all year.

India Standard Time (IST) covers: New Delhi, Mumbai, Bangalore, Chennai, Kolkata, Hyderabad, Colombo. It runs at UTC+5:30, fixed year-round with no DST change. Use the live clocks at the top of this page to see the current local time in both zones side by side.

Yes — since neither SAST nor IST observes DST, the offset is exactly 3h 30m ahead every day of the year without exception.

When creating a recurring meeting that spans SAST and IST, set the event timezone in your calendar app using the IANA timezone names: Africa/Johannesburg for SAST and Asia/Kolkata for IST. Using IANA names rather than fixed UTC offsets ensures the calendar app automatically adjusts future occurrences for any DST changes, so you never accidentally schedule at the wrong time after a clock transition. For a quick lookup of any specific time, the converter on this page is the fastest way to verify both sides before you send the invite.

No. South Africa abolished Daylight Saving Time in 1994, and SAST has remained at a fixed UTC+2 ever since. This applies to all South African cities — Johannesburg, Cape Town, Durban, and Pretoria all follow the same constant UTC+2 offset all year. South Africa's geographic position (spanning only about 13 degrees of longitude) also makes a single fixed timezone practical across the entire country.

India Standard Time is fixed at UTC+5:30 rather than a whole-hour offset because India uses a single nationwide timezone. Given the country's wide east-west geographic span, a half-hour compromise best approximates solar noon across most of India without forcing two separate zones. No part of India observes Daylight Saving Time, so IST stays at UTC+5:30 every day of the year. The practical effect: any conversion involving IST will always land on a :30-minute mark (e.g., 8:00 AM SAST = 11:30 AM IST).
