Q1: How do I convert time between different timezones?
Enter a date and time, select the source timezone (where the time is currently), select the target timezone (where you want to convert it), and click Convert. The calculator accounts for timezone offsets, including daylight saving time adjustments.
Q2: Does the calculator handle daylight saving time (DST)?
The calculator uses JavaScript's built-in timezone handling, which includes DST rules. However, DST rules can be complex and vary by location and year. For precise conversions, especially for historical dates, verify with official timezone databases.
Q3: What timezones are available?
The calculator includes major timezones: UTC, US timezones (Eastern, Central, Mountain, Pacific), European (London, Paris), Asian (Tokyo, Shanghai), and Australian (Sydney). For more timezones, you may need specialized timezone conversion tools.
Q4: How accurate are timezone conversions?
Conversions are accurate for current timezone rules. However, timezone rules can change (countries adjust DST, change timezones), and historical dates may have different rules. For critical applications, verify with authoritative timezone databases.
Q5: Can I convert times across the International Date Line?
Yes, the calculator handles date line crossings correctly. Converting from a timezone on one side of the date line to the other will correctly adjust both the time and the date. For example, converting from Tokyo to Los Angeles may show the previous day.
Q6: Why might my conversion seem incorrect?
Common issues: DST not applied correctly, timezone abbreviation confusion (e.g., EST vs EDT), or browser timezone data being outdated. Ensure you're using the correct timezone name and that your browser is updated. For critical conversions, double-check with multiple sources.
