This is a project I created many years ago, and haven't touched in about 13 to 16 years. It's mainly here for posterity, but if you still find it useful (and if it still works) then by all means feel free to make use of it. Any references to "6 times 9" are because that is the retired website where I was previously hosting things like this.


A dynamic countup and countdown timer with numerous noteworthy features:


Countdown with Years & Months

Countup with Years & Months

Countup with Weeks

Countup with Days


First put

<script src="dynupdown.js"></script>

in the head section, and then place

<script>start_counter(hour, minute, second, month, day, year, direction, beforetext, aftertext, eventname, compact, countername, notyears)</script>

wherever you want a timer to appear, editing it as appropriate. The configuration values are:

For example, the countdown to New Year's Day in the "Example" section above was generated using

<script>start_counter(0, 0, 0, 1, 1, "all", "down", "", "to the next New Year's Day.", "New Year's Day", "yes", "newyear", 0)</script>

and the first countup from the year 2000 was generated using

<script>start_counter(0, 0, 0, 1, 1, 2000, "up", "", "since the turn of the century.", "2000", "yes", "century", 0)</script>
