If someone went to do wudu and Isha ended at 12:20 am and they went to do wudu and somehow they didn’t realise the time and when they came out it was 12:19 am meaning they made it for one Rakat is their salah still valid they prayed 4 fard and 2 sunnah is their salah still valid as they went early for wudu but they didn’t realise the time went over. If they went to do wudu at 11:30 but because they weren’t aware of the time they didn’t know so is salah valid as they didn’t know and did it all unintentionally and they even went for salah early for wudu.
In the name of Allah, the Most Gracious, the Most Merciful
If one is mindful of their prayers, but occasionally falls asleep or miss salah or the salah time elapses because of shortcomings, then this won’t be considered as deliberately missing salah, and such a person will not be sinful, provided they are trying their best to pray their salah on time.
With regards to your question, one must read their prayers before their designated time.
Allah says in Quran
Indeed, salah is obligatory for the believers at prescribed times. Sura Nisa, Verse 103
If in a one-off situation the salah is delayed to the last minute, then if you have prayed the takbeer tahreema (Allah O Akbar) then your salah will be done for that time but if there is no time for takbeer tahreema then your salah is qadha and you will have to pray it at a later time.[i]
Only Allah knows best.
