Hi Java Script heroes 🙂 I have a really simple question but I just don't find any input on this in the forum. Here is what I would like to achieve: Within a function node, I would like to initiate different actions based on the time of day. Example: If time is between 9:00am and 7pm, activate Scene "Daylight" in living room. Would be nice if someone could show me a simple example how to do this that would be really nice 🤗

You should read up on the date() function in JavaScript. A good place to start is

A simple demo...

```auto
var now = new Date();
var hour = now.getHours();
if(hour >= 7 && hour < 19) {
  return msg;
}
return null; //halt flow, time must be before 7am or after 7pm

```

Alternative simple demo with 3 outputs (before 7am, between 7am~7pm, after 7pm)...

```auto
var now = new Date();
var hour = now.getHours();
if (hour < 7) {
  return [msg, null, null]; // it is before 7am - fire output 1
} else if(hour >= 7 && hour < 19 {
  return [null, msg, null] // it is between 7am~7pm - fire output 2
} else {
  return [null, null, msg]; // it must be after 7pm - fire output 3
}

```

Alternative: Using cron-plus to initiate the actions at whatever time you wish (graphically or programmatically - see built in demos & built in documentation)
