Countdown days, hours, minutes to 0

I have a start date and a duration. The duration is in the format of d:hh:mm. I am trying to countdown the d:hh:mm to 0. Not having much luck without using an end date. If anyone has suggestions please let me know. The other option would be to calculate the end date based on current date and adding in the d:hh:mm. I can do this in multiple cells doing day, hour, minutes separate but can't figure out how to do it in 1 cell.

Help with either option would be appreciated.

Thank you

Paste in a Routine Module :

Option Explicit

Public bTimerOn As Boolean

Sub ToggleTimer() ' This Sub will switch the automatic timer on if it was off before, and vice-versa
bTimerOn = Not bTimerOn

Refresh ' It calls the Refresh Sub
End Sub

Sub Refresh() ' This Sub calculates the sheet and tells Excel to call it again after 1 second

If bTimerOn Then ' If bTimerOn is True, start refreshing automatically
Application.OnTime Now + TimeValue("00:00:01"), "Refresh" ' The intervall is set to 1 second but can be changed variably
End If
End Sub
