What is a time-since calculator?
A time-since calculator measures how long ago a specific moment happened. It is the opposite of a countdown: instead of showing time remaining until a future event, it counts up from a past one. People use it to track anniversaries, sobriety milestones, project launches, age of equipment, or simply to answer "how long has it been since...?" Tickline's version gives both a calendar breakdown (years, months, days) and total counters (weeks, days, hours, minutes, seconds), updates every second, and lets you share the exact counter with a URL.

Frequently asked questions
What does 'time since' mean?
It is the exact elapsed duration between a past date/time and right now. Unlike a countdown, it counts up — useful for tracking anniversaries, sobriety, project age, or how long ago an event happened.
How accurate is the calculation?
The counter updates every second using your device's clock. Calendar breakdowns (years, months, days) respect real month lengths and leap years, so the display stays accurate over long periods.
Can I share a specific counter?
Yes. Enter a title and date, then click 'Copy shareable link'. The URL contains the start time, so anyone who opens it sees the same elapsed duration.
Is my data saved?
Only in your browser's local storage. Tickline does not send dates or titles to any server.
