| Parameter | Description | Example |
|---|---|---|
date | Target date/time (ISO 8601 format) | 2025-12-31T23:59:59 |
tz | Timezone (IANA format, defaults to UTC) | America/New_York |
title | Event title (max 50 chars) | New Year |
subtitle | Subtitle text, supports multiple lines (max 200 chars) | The countdown begins |
bg | Background color (hex without #) | 1a1a2e |
fg | Foreground/text color (hex without #) | ffffff |
units | Comma-separated time units | d,h,m,s |
end | Message when countdown ends (max 100 chars) | Happy New Year! |
| Unit | Abbreviations |
|---|---|
| Years | y, yr, yrs, years |
| Months | mo, mon, months |
| Weeks | w, wk, wks, weeks |
| Days | d, day, days |
| Hours | h, hr, hrs, hours |
| Minutes | m, min, mins, minutes |
| Seconds | s, sec, secs, seconds |
| Milliseconds | ms, milliseconds |
The following date formats are supported (interpreted as UTC unless tz is specified):
2025-12-31T23:59:59 - Full date and time2025-12-31T23:59 - Date and time without seconds2025-12-31 - Date only (midnight)The largest selected unit shows the total value. Smaller units show the remainder after subtracting larger units.
Example: If you select weeks and minutes for a 15-day countdown, you'll see "2 Weeks, 1440 Minutes" (not "2 Weeks, 30 Minutes").
URLs in the title, subtitle, and end message are automatically converted to clickable links. Just paste a full URL (starting with http:// or https://) and it will be linked.
The countdown ends at the exact target time. Hidden smaller units are accounted for using ceiling logic.
Example: If you select only minutes for a countdown to 12:30:45, you'll see "1 minute" until 12:30:45, then "0 minutes" briefly, then the end message.
This ensures the countdown reaches zero only when the target time has truly arrived.
