A simple countdown powered by Vue.js, inspired by TAKAHASHI's Digital Clock.
You can visit https://countdown.hikariyo.net/ or use your custom date like https://countdown.hikariyo.net?until=20240102.
For the until param, please provide either 8 digits for the date (YYYYMMDD) or 14 digits for the full timestamp (YYYYMMDDHHmmss).
It works best on PC, though mobiles are still adapted.
When the countdown ends, it will show 00d 00h 00m 00s rather than negative numbers.
