I'm not sure what you mean here. In importing time series data, gretl will typically pick up date information provided it is given in a consistent and reasonably standard form, in the first column of the imported data. If dates cannot be read in this way, they can be easily imposed using the "setobs" command. The two functions obsnum() and obslabel() can be used to move between a 1-based index of the observations and strings representing dates, such as "2012:01". And individual observations in a series can be picked out by date if required, as in scalar CPI_1980_1 = CPI[1980:1] Allin Cottrell
