Best time to call Manila from Mumbai
For most work calls, compare the normal business day in Mumbai (IST) with the business day in Manila (PHT). IST commonly covers South Asia, while PHT is mainly associated with Southeast Asia.
⚠️ Note: 2026-07-05 is not a normal workday in one or both regions based on their configured calendar. The overlap below should be treated as a reference, not a guaranteed office-hours window.
✅ The most practical overlap on 2026-07-05 is usually 9:30 AM - 3:30 PM IST, which corresponds to 12:00 PM - 6:00 PM PHT. This window sits inside the typical IST workday (9:30 AM - 6:30 PM) and the PHT workday (9:00 AM - 6:00 PM).
- DST Safety: Neither IST nor PHT uses Daylight Saving Time in our dataset, making business-hour relationships stable year-round.
- Bombay Stock Exchange (BSE): 09:15-15:30 local time in Mumbai.
- Philippine Stock Exchange (PSE): 09:30-15:00 local time in Makati.

Frequently Asked Questions
What is the time difference between IST and PHT?
During standard time, Philippine Time is 2.5 hours ahead of Indian Standard Time.
Does India observe Daylight Saving Time (DST)?
India does not observe Daylight Saving Time and has not done so since 1945. IST remains fixed at UTC+5:30 every day of the year, meaning the offset between India and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Why does IST have a 30-minute offset?
India chose the 82.5° East meridian — which passes through Mirzapur in Uttar Pradesh — as its central reference longitude, as it bisects the subcontinent geographically. That meridian sits exactly 5 hours and 30 minutes ahead of the Prime Meridian in Greenwich, producing the UTC+5:30 offset that has defined IST since 1906.
Does the Philippines observe Daylight Saving Time?
The Philippines does not observe Daylight Saving Time and has not done so since 1990, when the practice was last used as an energy conservation measure. PHT remains permanently fixed at UTC+8:00 every day of the year, meaning the offset between Manila and any DST-observing partner country shifts by one hour twice annually when those countries change their clocks — but PHT itself never moves.
Are PHT and SGT the same time?
Yes, Philippine Time (PHT) and Singapore Time (SGT) share the identical UTC+8:00 offset, and neither country observes Daylight Saving Time, making Manila and Singapore permanently synchronized on the same clock year-round. The same alignment holds with Malaysia (MYT), Greater China (CST), Hong Kong (HKT), and Western Australia (AWST) — all permanent UTC+8 zones.
