in a table with date and time, how to automatically delete first rows when time passed?

hello excel gurus !
with much respect for you guys , I would like to ask you if you could help me to automatically delete the first row in a table when the date and time columns are passed the current date.
I have a table with date column and time column, it's chronically arranged so the coming dates will be firsts and the distant dates will be last, and what I'm trying to do is that every date and hour that passed will be automatically deleted.(meaning all the row'll be deleted so there won't be any "passed" items)

it will be amazing if not only the first row will be deleted , but it will also show a popup message that displaying the 2nd column of the row - which contain the assignment item itself (it's description).

that'll really awesome and I can't put it on words how grateful I'm for your highly skilled help, and bright solutions very appreciated - thanks for any help.

btw- the reason that I'm trying to have this , is because I really strive to have a system that could display the first 10 signal items (it's like todo's but not exactly because it's dynamically changing all the time), so I could act upon them and those would pushed automatically upward based on the time.
I've added the excel file - it demonstrate visually which better than my words.

netanel.
