Understanding the 7 AM PST to EST Conversion
Time Difference
Pacific Standard Time (PST) is 3 hours behind Eastern Standard Time (EST). This means that 7:00 AM PST is equivalent to 10:00 AM EST. This time difference remains constant throughout the year, even during Daylight Saving Time changes when they become PDT and EDT respectively.
Business Impact
The 7 AM PST to 10 AM EST conversion is particularly important for business communications between the West and East coasts of the United States. When the workday begins at 7 AM in California, colleagues in New York are already three hours into their day at 10 AM.
Daylight Saving Time
Both PST and EST observe Daylight Saving Time, becoming PDT (Pacific Daylight Time) and EDT (Eastern Daylight Time) respectively. The 3-hour difference remains constant, as both regions adjust their clocks forward in spring and backward in fall on the same dates.

Planning Meetings Across Time Zones
When scheduling meetings between PST and EST time zones, it's important to find overlapping business hours. A meeting at 7 AM PST (10 AM EST) works well for both coasts, as it's early enough for the West Coast while being well into the workday for the East Coast.
Interesting Time Zone Facts
The continental United States spans four time zones: Pacific, Mountain, Central, and Eastern.
The concept of standardized time zones was first proposed by Canadian Sir Sandford Fleming in the late 1870s.
Before standardized time zones, each city maintained its own local time based on the sun's position.
