↑The Razadarit Ayedawbon chronicle (Pan Hla 2005: 37) says he was born on Friday, 7th waxing of Late Tagu 635 (Thursday, 15 March 1274). But 635 ME was likely a typographical error. The chronicle (Pan Hla 2005: 16) says he had an elder brother Ma Gadu and a younger sister Hnin U Yaing. The chronicle's later narrative (Pan Hla 2005: 37) again mentions twice that Gada was U Yaing's older brother. Since Gadu was born in 1253 per (Pan Hla 2005: 36), and since Hnin U Yaing was already in her marriage age in 1281/82 per (Pan Hla 2005: 21–23), it was highly unlikely that Gada would have been born 21 years later in 1274, and Hnin U Yaing even later. Instead, the birth date was more likely Friday, 7th waxing of Late Tagu 615 ME (Friday, 27 March 1254), date translated per (Eade 1989: 100).
↑The chronicle Razadarit Ayedawbon (Pan Hla 2005: 37, 39) says Hkun Law died in 672 ME, and soon after Saw O ascended the throne on Saturday, 6th waning of Tagu 673 ME (10 April 1311). It means Law most probably died in the last weeks of 672 ME (March 1311).
↑Since Law was 56 (in his 57th year), he must have died by 6th waxing of Late Tagu 672 ME (26 March 1311). Per (Pan Hla 2005: 39), Saw O became king on Saturday, 6th waxing of Tagu 673 ME (10 April 1311).
