Prayer times?

[Bungy Dude]

Assalamu alaikum brothers and sisters

Please can you help to fill in the below. (Hanafi madhab) .

I have a prayer timetable but want to know parameters really since I find it difficult to meet the jamaat times when at work. Any help to be greatly appreciated.

1. Fajr can be prayed between Sun rise and ________ .
2. Zuhr can be prayed between _______ and ________.
3. Asr can be prayed between Asr beginning time and ________.
4. Magrib between Magrib jamaat time and ________.
5. Isha between Isha beggining time and _________.

Also, if I miss the prescribed time period, how many rakats do I read for qaza? is it the full rakats e.g 12 for zuhr or just the 4 farz for zuhr?

and do you get guna for reading qaza or is it that you dont get the full neki?

Jazakallah
