How to check the rotation of a transform

Hello I wanted to know if their is a way to check to see at what point in rotation is an object. For example using an if statement to see if thee sun is at 270 degrees and it's rotation and then Debugging "It's noon". The reason why I need this is because I'm trying to track the days in game but first I need to have a clock.

I figured the best way to script a change in the day is to trigger it when the sun is at the Midnight(90 degrees) position.

I hope my question is clear, and thank you ahead of time

Here's the script btw: using UnityEngine; using System.Collections; using System.Collections.Generic; using System;

 public class GameTime : MonoBehaviour {
     public enum TimeOfDay
         {
         Idle,

         }
     public Transform[] sun;
     public float dayCycleInMinutes = 1;    //Tells of how many IRL minutes is a whole day in game
 
     public float sunRise;                   //the time of day that we start the sunrise
     public float sunSet;                    // The time of day that we start the sun set
     public float skyboxBlendModifier;       //The speed at which the textures in the skybox blend
