Where you'll actually use this
Time converters handle durations — seconds, minutes, hours, days, weeks, months, and years. Useful for scheduling, project planning, and physics calculations.
- Project planning
Convert sprint durations between days and weeks; estimate hours-of-work against calendar time.
- Media & storage
Video durations, transcription time, and audio runtime often need conversion to total seconds for tooling.
- Science
Half-lives, orbital periods, and reaction times span femtoseconds to gigayears.
Common mistakes to avoid
- A month isn't a fixed length
Calendar months vary from 28 to 31 days. Converters typically use 30.44 days as an average.
- Year as 365 days
A Julian year is 365.25 days. Skipping the quarter introduces a day of error every four years.
