How Timezone Conversion Works

1 Standard Coordinated Time (UTC)

Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is not adjusted for daylight saving time, making it the perfect reference baseline for all timezone calculations.

2 Daylight Saving Time (DST) Transitions

Many countries shift their clocks forward in spring (saving daylight) and back in autumn. Because our timezone calculator is built using native system databases, it automatically tracks these transition dates so you never plan a meeting off by an hour.

3 Finding overlapping Business Hours

To find ideal meeting slots, look for the overlapping Green blocks in the scheduler. This represents standard working hours (9:00 AM - 5:00 PM local time) for all participant regions, minimizing late-night or early-morning calls.
