I have an index, i have implemented ILM on that. I am not seeing index is not moving to warm phase after reaching out 8 days old. There are no errors to.

```auto

  "emailer-lifecycle-policy" : {
    "version" : 1,

            }
          }
        },

            },
            "rollover" : {

            }

        },

            "delete" : {
              "delete_searchable_snapshot" : true
            }
          }
        }
      }
    },
    "in_use_by" : {
      "indices" : [
        "emailer-logs-2023.02.06-000001",
        "emailer-logs-2023.02.06-000002"
      ],
      "data_streams" : [],
      "composable_templates" : [
        "emailer-index-template"
      ]
    }
  }
}

```

This is the policy. Index got created on 6th of this month so it has to reach to warm phase on 14th or 15th, but still i see data in in hot phase.

Hi @rahul_sirugudi  
I think you are falling fir a common misconception.

ILM moving to warm is calculated from the rollover date.

So index created on 6th.  
Hot says rollover after 7days  
So index rolls over on 13th  
Warm says 8 days from rollover so that will be 13th + 8 days ..  
So around the 21st.

See here

> The min\_age value is relative to the rollover time, not the index creation time

You can also use the `_ilm/explain` API to get a better explanation of what it's going on.
