this is a basic countdowntimer that has the ability to countdown to a specified time. it is to be used client side.
i hope to be able to use this for a year with as little maintenance as possible so i have identified some issues to be addressed.
see if you can address these issues to increase the functionality and longevity
issue 1
create a way for there to be multiple preset times
isue 2
find a way to create notifications across multiple devices using browser capabilities
issue 3
make it easier to use on mobile devices
issue 4
add a playlist that changes for each date(all sounds used muts be open source and attributions made as necessary)
