Convert IST to CET
Compare India Standard Time and Central European Time with a live conversion table, meeting planner, and export options.
How IST to CET Works
Convert India Standard Time (UTC+5:30) to Central European Time (UTC+1) using the current offset difference. The converter updates automatically for Central European daylight saving changes where applicable.
Hour-by-Hour Time Table
Use the visual grid to compare IST and CET hour by hour across the day. Check overlapping business hours, then export selections as ICS or send to Google Calendar and Gmail.
Schedule Meetings Across Zones
Find suitable meeting times between India Standard Time and Central European Time with automatic DST-aware adjustments. Time data is tracked against the IANA timezone database for accuracy and historical rule changes.

Open the IST to CET converter: Visit https://www.xconvert.com/time-converter/ist-to-cet-converter when you need to line up India Standard Time with Central European Time for a client call, supplier update, or remote team handoff between India and Europe. The page opens with India Standard Time and Central European Time in a visual comparison grid, so you can immediately see how India’s UTC+5:30 schedule aligns with CET at UTC+1 across the day.
Add relevant comparison cities: Click + Add City and search for cities that matter to your workflow, such as Mumbai or New Delhi for India-based operations and Berlin, Paris, or Milan for European finance, manufacturing, and customer support teams. This is especially useful for companies coordinating software delivery from India with teams in Germany, France, Italy, or other CET countries including Austria, Belgium, Netherlands, Poland, Sweden, and Switzerland.
Select a working time window: Click Select, then drag across the grid to highlight a time range in purple and compare the hours visually; you can resize the range with the side handles or move it by dragging the center. For example, dragging from 9:00 IST to 12:00 IST shows 4:30 CET to 7:30 CET, while 15:00 IST to 18:00 IST maps to 10:30 CET to 13:30 CET, which is far more practical for cross-border meetings because it lands inside the European business day.
Export and share the result: After selecting a range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link to send the chosen slot to colleagues or clients. This is useful when an India-based engineering team wants to lock in a Europe-facing product review, because the calendar export preserves the meeting in each participant’s local time without manual re-entry.
Understanding the IST to CET Time Difference
India Standard Time (India Standard Time, UTC+5:30) is 4 hours 30 minutes ahead of Central European Time (CET, UTC+1). That means CET is 4 hours 30 minutes behind India Standard Time, so a morning in India lands much earlier in Central Europe: 9:00 IST = 4:30 CET, 12:00 IST = 7:30 CET, 15:00 IST = 10:30 CET, and 18:00 IST = 13:30 CET.
India Standard Time does not observe daylight saving time, so India keeps the same UTC+5:30 offset year-round. CET is a standard-time abbreviation, and its daylight-saving counterpart is CEST, which means the IST-to-Europe gap does not stay identical across the full year when European countries switch away from standard time.
This matters for scheduling across the many countries that use CET in standard time, including Germany, France, Italy, Spain, Netherlands, Belgium, Switzerland, Austria, Sweden, Norway, Poland, Denmark, Czechia, Hungary, Slovakia, Slovenia, Croatia, Serbia, Bosnia and Herzegovina, Montenegro, North Macedonia, Albania, Andorra, Liechtenstein, Luxembourg, Malta, Monaco, San Marino, Vatican, Gibraltar, Tunisia, Algeria, and Svalbard and Jan Mayen. If you regularly coordinate with European sales desks, logistics teams, consulting firms, or manufacturing partners, the difference shown on this page applies specifically when Central European locations are on CET rather than CEST.
Best Times for Calls and Meetings Between IST and CET
India Standard Time (India Standard Time, UTC+5:30) works best with Central European Time when you schedule in the later part of the Indian workday, because that lines up with the morning to early afternoon in Central Europe. The clearest examples are 15:00 IST = 10:30 CET and 18:00 IST = 13:30 CET, both of which fit normal office hours for teams in India and in major CET business centers such as Berlin, Paris, Amsterdam, Milan, Brussels, Zurich, and Vienna.
Early India mornings are usually poor for live collaboration with Central Europe because they fall before the European workday starts. For example, 9:00 IST = 4:30 CET and 12:00 IST = 7:30 CET, which can be too early for finance teams, agency partners, procurement managers, or customer success staff in CET countries.
For recurring meetings, a practical pattern is to place shared sessions in the India afternoon so Europe joins in the same calendar day during its morning or lunch-adjacent hours. This is useful for SaaS companies with engineering in India and customers in Germany or France, e-commerce operations coordinating fulfillment with European partners, and consulting teams preparing handoffs between India delivery centers and CET-based client stakeholders.
Frequently Asked Questions
What is the time difference between IST and CET?
India Standard Time (India Standard Time, UTC+5:30) is 4 hours 30 minutes ahead of Central European Time (UTC+1). Put another way, CET is 4 hours 30 minutes behind India Standard Time, so schedules in India need to shift later in the day to overlap comfortably with European office hours.
When is 9 AM IST in CET?
9:00 IST = 4:30 CET. This is usually too early for most business meetings in Central Europe, especially for teams in Germany, France, Italy, Belgium, Netherlands, Switzerland, or Austria that begin work closer to standard morning office hours.
Does the difference between IST and CET change during daylight saving time?
India Standard Time does not observe daylight saving time, so India stays on UTC+5:30 all year. CET is the standard-time label, and its daylight-saving counterpart is CEST, so the IST-to-Europe difference changes when Central European countries move off CET and onto CEST rather than staying on standard time.
What is the best meeting time between IST and CET?
The most practical overlap usually falls in the afternoon in India Standard Time, because that becomes the morning to early afternoon in Central European Time. The examples on this page show why: 15:00 IST = 10:30 CET and 18:00 IST = 13:30 CET, both of which are much better for joint calls than 9:00 IST = 4:30 CET.
When is 12 PM IST in CET?
12:00 IST = 7:30 CET. That can work for very early starts in Central Europe, but it is often still before normal meeting hours for commercial, legal, HR, and operations teams across CET countries.
When is 3 PM IST in CET?
15:00 IST = 10:30 CET. This is one of the most useful conversion points for real work because it places India in mid-afternoon while Central Europe is in a normal late-morning slot, making it suitable for project reviews, vendor calls, and client demos.
Is IST India Standard Time or Irish Standard Time?
On this page, IST means India Standard Time (UTC+5:30). If you need the Ireland meaning, use Irish Standard Time (UTC+1) at /time-converter/ist-ireland-time-zone; if you need the Israel meaning, use /time-converter/ist-israel-time-zone.
Which countries use CET?
Central European Time is used across a large part of Europe and nearby regions, including Albania, Algeria, Andorra, Austria, Belgium, Bosnia and Herzegovina, Croatia, Czechia, Denmark, France, Germany, Gibraltar, Hungary, Italy, Liechtenstein, Luxembourg, Malta, Monaco, Montenegro, Netherlands, North Macedonia, Norway, Poland, San Marino, Serbia, Slovakia, Slovenia, Spain, Svalbard and Jan Mayen, Sweden, Switzerland, Tunisia, and Vatican. For businesses in India, this broad coverage makes CET a common reference point when dealing with European customers, distributors, and regional headquarters.
