Work out the exact time between two dates, down to the second. Use "Now" for a quick time-since or time-until calculation.
Times are optional — leave them blank to treat a date as starting at midnight.
"2 years, 3 months, 14 days" accounts for the real, uneven length of months and years — it's not just total days divided by 30 and 365. That's why it matches how you'd naturally describe someone's age or how long ago something happened.
Total days, weeks, hours, minutes and seconds are the exact same span of time expressed as one single unit each — useful when you need a single number rather than a breakdown.
Set the past date as "From" and tap Now on "To" for time elapsed since something happened. Flip it around — Now as "From", a future date as "To" — for a countdown instead.
