[ULPIANUS libro quinquagensimo ad Sabinum. ] §45.1.47.prQui sic stipulatur: 'quod te mihi illis kalendis dare oportet, id dare spondes?' uidetur non hodie stipulari, sed sua die, hoc est kalendis.
[ULPIANUS, in the fiftieth book on Sabinus.] He who stipulates thus: 'Do you promise to give that which you ought to give to me on those Kalends?' is deemed to stipulate not today, but on its own day, that is, on the Kalends.
