With [MomentJS](https://curiouslychase.com/engineering/momentjs/) ([JavaScript](https://curiouslychase.com/posts/javascript/)), you can check if two times are the same with the `isSame` method.

First, instantiate `moment` with the date you want to check:

```js
const someDate = "2021-07-14";
const currMoment = moment(someDate);
```

Then use the `isSame` method: 

```js
const someDate = "2021-07-14";
const currMoment = moment(someDate);

const anotherDate = "2021-07-13";

const isSameDay = currMoment.isSame(anotherDate, "day") // false
const isSameMonth = currMoment.isSame(anotherDate, "month") // true
```

I use this heavily in my [Dataview (Obsidian)](https://curiouslychase.com/posts/dataview-obsidian/) queries for [Obsidian](https://curiouslychase.com/tools/obsidian/).
