Also, her dates of birth and death are unknown, but it is suggested that she was about 30 years old in 1008, based on historical materials and her works; by counting backwards from that age, she would have been born around 979 and died around 1016.
また生没年も伝わっていないが、資料・作品等から寛弘5年（1008年）に30歳位と推測されるので、逆算して天延元年（979年）頃生？-長和五年（1016年）頃没？と推定されている。
