Time relationship
Formula
destination hour = (local hour + offset) mod 24= 20
Note
This is a simplified model: it uses fixed conversions (60 minutes per hour, 24 hours per day, 7 days per week, 365 days per year) and ignores leap years, daylight saving changes, public holidays and irregular month lengths. Check the result against a real calendar before relying on it.

How does the calculator convert time between offsets?+
It takes the source time, adds or subtracts the difference between the two UTC offsets, and adjusts the calendar date if the result crosses midnight.
Why is UTC used as the reference point?+
UTC is a fixed, universal standard that doesn't observe daylight saving time, making it a stable reference for converting between any two time zones regardless of their individual local rules.
Can converting between offsets change the date, not just the time?+
Yes, if the offset difference is large enough or the source time is close to midnight, the converted time can fall on the previous or next calendar day.
How do I handle a time zone that uses a half-hour or 45-minute offset?+
Enter the precise offset (like UTC+5:30 for India) rather than rounding to the nearest whole hour, since the calculator needs the exact offset to produce a correct converted time.
Does this calculator account for daylight saving time automatically?+
It converts based on the offset you provide; since offsets can shift seasonally in regions that observe daylight saving time, make sure to use the offset that applies on the specific date you're converting for.
