deno_dayjs
Provides dayjs 1.10.7
for Deno.
Day.js is a minimalist JavaScript library that parses, validates, manipulates, and displays dates and times for modern browsers with a largely Moment.js-compatible API. If you use Moment.js, you already know how to use Day.js.
More info or API to see this way.
