Frequently asked questions
Does it roll over across days?
Yes. Adding hours or minutes that cross midnight advances the date automatically, and subtracting rolls it back.
Can I start from the current time?
Yes — press the Now button to fill in the current date and time, then add or subtract from there.
Is my time zone considered?
The calculation uses your device's local time. To compare across time zones, use the Time Zone Converter.
