Frequently Asked Questions
What dates are supported?
Any date that your browser can handle. We use the standard JavaScript Date object, which typically supports a wide range of years.
Is my data sent to a server?
No. The calculation happens in your browser. No dates are uploaded.
Which timezone is used?
We interpret the date in your local timezone (as set on your device). So "January 1, 2020" is the first day of 2020 in your locale.
