“est to ph time” is a phrase used to inquire about the time difference between Eastern Standard Time (EST) and Philippine Time (PH). EST is observed along the eastern coast of North America, while PH is the standard time zone for the Philippines. The time difference between EST and PH is 12 hours, with PH being 12 hours ahead of EST. This means that when it is 12:00 PM in EST, it is 12:00 AM the following day in PH.
