Timezone converter
IST to WEST currently uses India Time in Asia/Kolkata and Western European Time in Africa/Casablanca as the live reference pair, with a -4h 30m live gap. IST to WEST matters whenever Mumbai and Casablanca need to coordinate across a -4h 30m gap. The IST side covers India and Israel, while WEST covers Morocco and Portugal — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.

Based on the busiest city and zone usage found in the current dataset.
IST (Mumbai, +05:30) to WEST (Casablanca, +01:00) is currently a -4h 30m conversion. Live coverage on the IST side is anchored by Mumbai, Delhi, Bengaluru, and Hyderabad; the WEST side draws from Casablanca, Rabat, Fes, and Tangier.
IST to WEST matters whenever Mumbai and Casablanca need to coordinate across a -4h 30m gap. The IST side covers India and Israel, while WEST covers Morocco and Portugal — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.
This pair runs between Europe or Africa and Asia or the Pacific. With -4h 30m between them, the late European morning often catches the early Asian evening, which is the practical window for cross-region operations and travel planning.
WEST follows seasonal clock changes through Africa/Casablanca, while IST stays on a fixed offset year-round. The result is a gap that quietly shifts by an hour twice a year — short by an hour in winter (or summer, depending on hemisphere) and back to normal afterwards.
IST and WEST sit 4h 30m apart, with about 3.5h of shared 9-to-5 time. That is enough room for one daily standup plus one focused working session, which is what most cross-region teams actually use this overlap for.
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.
WEST coverage is led by Casablanca, Morocco, Rabat, Morocco, Fes, Morocco, and Tangier, Morocco, with 2 more anchoring the wider label family. Combined with the IST side, this conversion ends up describing cross-region coordination that uses the morning-on-one-side, afternoon-on-the-other window for live work.
