How to Subtract or Add Date in Javascript
Jasser Mark Arioste
I've seen a lot of tutorials on the internet on how to subtract date using plain javascript.This example explains the exact steps on how to do that. While it's useful for understanding how to work with dates on a foundational level, its not really practical when developing applications. In my opinion, it's better to use a date utility library like dayjs.
Dayjs doesn't only allow us to add or subtract dates, but also compare and format dates, and all other kinds of stuff that you can think of.
Pros of using dayjs #
- Very lightweight library (2kb)
- Faster than any other date manipulation library like date-fns or luxon.
- Intuitive api
- You can add/remove features using its plugin system

using yarn or npm
yarn add dayjs or npm i dayjs123
