Shared working hours
They do not overlap at all. A 09:00–17:00 working day in Philippine Time ends 3 hours before the Central Time one begins, so any live call sits outside somebody's working hours.
The shortest reach is the edges: early morning in PHT against late evening in CST, or the other way round.
When the difference changes
The two zones move their clocks on different dates, so the gap takes more than one value. These are the stretches of 2026:
| Dates | CST is | Why |
|---|---|---|
| 1 January – 8 March | 14 hours behind | — |
| 8 March – 1 November | 13 hours behind | Central Time clocks go forward one hour |
| 1 November – 1 January | 14 hours behind | Central Time clocks go back one hour |
Dates are Philippine Time local dates for 2026. Transition dates move by a few days from year to year; the rule each country follows does not.
About Philippine Time
The Philippines is a fixed UTC+8. It is a heavily quoted zone in outsourcing schedules, which is why the pairs from it to North America are among the most searched on this site.
Cities on this clock: Beijing, Shanghai, Guangzhou, Shenzhen, Chongqing, Taipei, Hong Kong, Singapore.
Watch out: Philippine Standard Time is often written PST locally — the same letters as US Pacific Standard Time, which is sixteen hours behind it.
About Central Time
Central Time covers the middle third of North America, from Manitoba down through Texas. It is UTC−6 as CST and UTC−5 as CDT, changing on the same dates as the other US zones — so the one-hour steps between Pacific, Mountain, Central and Eastern hold all year and never briefly collapse.
Cities on this clock: Chicago, Houston, San Antonio, Dallas, Austin, Nashville, Minneapolis, New Orleans.
Watch out: CST is also the abbreviation for China Standard Time, which is UTC+8 — fourteen hours away from this one. This page is the North American zone.
How the difference is worked out
The gap between Philippine Time and Central Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 13 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.
With both zones on their own standard time — daylight saving not in force anywhere — Central Time is 14 hours behind Philippine Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.
Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Asia/Manila and America/Chicago. Nothing is looked up on a server and nothing about your visit is recorded.
Is CST ahead of or behind PHT?
Central Time is 13 hours behind Philippine Time for 238 days of the year, and takes 2 different values across the year.

What time is 9 AM PHT in CST?
