To knowe which day is lik to which day as of
lengthe.
Loke whiche degrees ben ylike fer fro the hevedes of Cancer
and Capricorne, and loke when the sonne is in eny of thilke
degrees; than ben the dayes ylike of lengthe. This is to seyn
that as longe is that day in that month, as was such a day in
such a month; there varieth but litel.
Also, yf thou take 2 dayes naturales in the yere ylike fer
fro either point of the equinoxiall in the opposyt parties, than as
longe is the day artificiall of that oon day as is the night of
that othir, and the contrarie.
