Convert date & time between multiple global timezones with a real-time Daylight Saving Time (DST) slider.
A timezone is a geographical region that observes a uniform standard time for legal, commercial, and social purposes. Standard time zones are defined by offsets relative to Coordinated Universal Time (UTC), ranging from UTC-12:00 to UTC+14:00.
Daylight Saving Time is the practice of advancing clocks forward by one hour during warmer months so that darkness falls at a later clock time. Clocks are adjusted back in autumn. Not all countries observe DST, causing differences to change dynamically.
While most timezones use increments of whole hours, some countries (like India, Nepal, and parts of Australia) utilize fractional offsets (e.g., India is UTC+5:30) to better align with the natural solar day.
