Best time to call Manila from Tokyo
For most work calls, compare the normal business day in Tokyo (JST) with the business day in Manila (PHT). JST commonly covers East 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 10:00 AM - 6:00 PM JST, which corresponds to 9:00 AM - 5:00 PM PHT. This window sits inside the typical JST workday (9:00 AM - 6:00 PM) and the PHT workday (9:00 AM - 6:00 PM).
- DST Safety: Neither JST nor PHT uses Daylight Saving Time in our dataset, making business-hour relationships stable year-round.
- Tokyo Stock Exchange (TSE): 09:00-15:00 local time in Tokyo.
- Philippine Stock Exchange (PSE): 09:30-15:00 local time in Makati.

Frequently Asked Questions
What is the time difference between JST and PHT?
During standard time, Philippine Time is 1 hours behind Japan Standard Time.
Does Japan observe Daylight Saving Time?
Japan has not observed Daylight Saving Time since 1951, when the practice introduced during the Allied occupation was abolished by the Japanese government. JST has remained fixed at UTC+9:00 ever since, and there is no current legislation to reintroduce DST in Japan.
Is JST the same as Korean Standard Time (KST)?
Yes, South Korea's Korean Standard Time (KST) operates at the same UTC+9:00 offset as JST, and South Korea also does not observe Daylight Saving Time. The two countries share an identical clock year-round, which simplifies scheduling for the significant trade, technology, and cultural exchange between Tokyo and Seoul.
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.
