Is there a way to get the day of the year (like 120 out of 365) from the moment node ?

Have a look at the help: [Moment.js | Docs](https://momentjs.com/docs/#/displaying/format/)  
Looks to me that **DDD** will do the job.

A quick google search shows many ways to do this. Here is an example

```auto
[{"id":"b6baf30f311ebf45","type":"function","z":"4e2a697d7291533e","name":"","func":"const dayOfYear = date => Math.floor((date - new Date(date.getFullYear(), 0, 0)) / (1000 * 60 * 60 * 24));\nmsg.payload = dayOfYear(new Date());\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[],"x":420,"y":300,"wires":[["94d616a4ab53c479"]]},{"id":"a1986fa9bc2b4dce","type":"inject","z":"4e2a697d7291533e","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":200,"y":300,"wires":[["b6baf30f311ebf45"]]},{"id":"94d616a4ab53c479","type":"debug","z":"4e2a697d7291533e","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":570,"y":300,"wires":[]}]

You have to add moment to the start up tab of the function node.  
e.g.

```auto
[{"id":"a1986fa9bc2b4dce","type":"inject","z":"65617ffeb779f51c","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":180,"y":1380,"wires":[["b6baf30f311ebf45"]]},{"id":"b6baf30f311ebf45","type":"function","z":"65617ffeb779f51c","name":"","func":"msg.payload = moment().format(\"DDD\"); // \"2014-09-08T08:02:17-05:00\" (ISO 8601, no fractional seconds)\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","libs":[{"var":"moment","module":"moment"}],"x":400,"y":1380,"wires":[["94d616a4ab53c479"]]},{"id":"94d616a4ab53c479","type":"debug","z":"65617ffeb779f51c","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":570,"y":1380,"wires":[]}]

@E1cid flow works fine for me.

Just a thought... Have you got the moment node installed via the palette manager ?

 ![moment_palette](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/1/8/1895a952fe048b2a1ea0a1fcd501455cc88851e5.png)

Is functionExternalModules set to true in your settings.js.  
[Writing Functions : Node-RED](https://nodered.org/docs/user-guide/writing-functions#using-the-functionexternalmodules-option).  
Also you can use JSONata in the function node see [here](https://discourse.nodered.org/t/using-moment-js-in-a-function-node-nr-3-01-2023/76916/7)

Install the node with the palletmanager as Dave suggested.

Fill in the _output forma_t of the node like this with the **DDD** and you are done.
