Here is a link to basic data on this pair of K stars. A’s luminosity is 0.09, therefore its life zone boundaries would be around 0.21 and 0.45 AU, with Earth twin distance at 0.3. An Earth twin would have a 59-Earth-day year. B has a luminosity of 0.04, with the life zone stretching from 0.14 to 0.3 AU, with Earth twin distance at 0.2. A planet there would have a 33-day year.
