Verb pattern

[Jurohkl]

Hi
Could you please help me solve this dilemma I have. What is the difference between these sentences:
I was supposed to have arrived on the 14th of October.
I was supposed to arrive on the 14th of October.

I found the first sentence in a grammar book and I wonder if it has the same meaning as the second sentence that I made up.
Thank you very much for your answer.

Welcome to the forum, Jurohkl.

The second sentence should read 'I was supposed to arrive . . . .'

Please note that I was supposed to have arrived would have been a better title for your thread.

Yes, I am sorry for the mistake. But, is there any difference in the meaning of these two sentences or both of them could be used?

I was supposed to have arrived on by the 14th of October. The obligation was to arrive no later than the 14th. It would have been acceptable to arrive before that date.
I was supposed to arrive on the 14th of October. No earlier, no later.
