Keith Wood Countdown Timer

Keith Wood Countdown Timer

Hi all,

I am completely new to jQuery so I don't know how to read the codes. I got this countdown timer from Keith Wood. And I would like to change the end date. Not sure how to go about doing it. I had searched in other forums such as stackoverflow and within this forum but I cannot find the exact code to change.

I found these links thus far:

https://forum.jquery.com/topic/need-help-to-change-keith-wood-countdown-timer

Would someone be able to help?

Not sure what I need to paste, so I included the code as attachment. Thank you in advanced.
