Do you really need to convert your data to time series/xts/zoo? I don’t know you try what kind of an analysis but perhaps you don’t have to.

If you really have to convert to xts/zoo, why don’t yo set each year to first day of January and use it as is? For instance,

index, cnsm, incm, wlth
1980-01-01, 174, 53.4, 60.3
1981-01-01, 175, 53.7, 60.5
1982-01-01, 175, 53.5, 60.2
…..
