Frequently Asked Questions
How are months and years calculated?
Months and years use average calendar lengths (30.44 and 365.25 days) since calendar months vary in length. For exact calendar-date math, use the Date Difference Calculator instead.
Is this the same as the Date Difference Calculator?
No. This tool converts a duration between units (e.g. minutes to hours); the Date Difference Calculator finds the time between two specific calendar dates.
Does my data get uploaded anywhere?
No. The conversion happens entirely in your browser using JavaScript -- nothing is ever sent to a server.
