Time Ago Calculator
See how long ago a past date and time was, in a human-friendly format.
"That was 3 years and 2 months ago" reads more naturally than a raw number of days — the human-friendly "time ago" format is how we actually think about the past. Working it out by hand across years, months and days is fiddly, especially with varying month lengths.
Enter a past date and time and this tool shows how long ago it was in a readable breakdown of years, months, days, hours and minutes, plus the total in days. It's handy for anniversaries, tracking how long since an event, or adding relative timestamps to notes.
