Thanks Brother for your efforts.
Well, in Western Countries, we normally have TWO or THREE Friday Prayers due to space limitations and working day.
Additionally, most of the time we display Iqamah Times which is normally kept in ming working class and office timings.
In my humble opinion You may want to program as follow to display on FRIDAY only.
Friday Prayer 12:30 1:30 2:30
or
Khutbah 12:30 1:30 2:30
Khutbah timings are different than Iqamah timings for Zahur in week days.
Like we have 3 prayers for Friday – you may want to provide additional 3 columns in excel to be uploaded with Friday Khutbah timings. If someone has 2 prayers – they fill only 1st & 2nd Khutbah similarly if someone only have one, they only fill 1st Khutbah column.
Jazakallah
