Follow these practices to keep calculations audit-ready.
Record daylight saving context
The days calculator handles DST changes automatically, but adding a note to your plan reassures stakeholders that you considered it.
Round intentionally

Share both day and hour totals
The dual display acts as a built-in double-check and lets operations align their hourly staffing plans with the day-level view.
Frequently Asked Questions
Answers target planners, logistics teams, and community organizers.
Does the days calculator handle leap years?

Can I enter partial days?
Absolutely. Enter values such as 1.75 to represent one day and eighteen hours. The results show hours and minutes so you can verify the math.
Will the result respect my local timezone?
