Fasting Ramadan, standing its nights and the Night of Decree

صيام رمضان وقيامه وقيام ليلة القدر

Three consecutive texts in Sahih al-Bukhari share one wording for the result: whoever fasts Ramadan with faith and hope of reward has his past sins forgiven Sahih al-Bukhari 38 — forgiveness of past sins, likewise whoever stands its nights in prayer Sahih al-Bukhari 37 — forgiveness of past sins, and likewise whoever stands the Night of Decree Sahih al-Bukhari 35 — forgiveness of past sins. The result is a clearing of what went before, not a number subtracted, so the calculator shows it in words.
