We present the age distribution function for Large Magellanic Cloud (LMC) clusters obtained from a relationship between their integrated U BV colours and age. We discuss further the results by Chiosi et al. (1988) on the nature of the bimodal distribution of the (B - V) colours for LMC clusters. Their conclusion that bimodality in the colour stems from the combined effect of the age distribution function and the rate at which clusters change colour with age, is revisited. The result of our analysis shows that the age distribution is the sole agent and that a real age gap is present. Finally, we draw some conclusions about the efficiency of cluster formation and disruption in the LMC.
