Did you right click on the sheet tab and select view code, then place that
code in the resulting module.

Are Events Enabled?

Run code like

sub MakeitRun()
Application.EnableEvents = True
End sub

Your code ran for me.

it follows below my macro:

Private Sub Worksheet_Calculate()

Dim col1
Dim col2
Dim col3
Dim lin

lin = 13
col1 = 8
col2 = 12
col3 = 13


For lin = 13 To 2057

If Cells(lin, col1) = 1 And Cells(lin, col3) = 0 Then
Cells(lin, col3) = 1
Cells(lin, col2) = Now()
End If

If Cells(lin, col1) = 0 Then
Cells(lin, col3) = 0
Cells(lin, col2) = ""
End If

If Cells(lin, col1 + 1) = 1 And Cells(lin, col3 + 2) = 0 Then
Cells(lin, col3 + 2) = 1
Cells(lin, col2 + 2) = Now()
End If

If Cells(lin, col1 + 1) = 0 Then
Cells(lin, col3 + 2) = 0
Cells(lin, col2 + 2) = ""
End If

If Cells(lin, col1) = 1 And Cells(lin, col1 + 1) = 1 Then
Cells(lin, 11) = Abs(Cells(lin, 14) - Cells(lin, 12))
Else
Cells(lin, 11) = ""
End If

Next

End Sub

for an overview of events at Chip Pearson's site.

Sounds like you want to use the Change event or the Calculate event.

Private Sub Worksheet_Change(ByVal Target As Range)

End Sub

Private Sub Worksheet_Calculate()

End Sub

Properly structured and located, these can be useful with the situation
you
describe.

I wrote a code of macros in the VBA and it does not execute
automatically
when I give a manual command to it execute, the macro functions
normally
but
it never functions with the update of a cell of excel
