please refer to this thread having a similar issue :thread

P.S. the due date you have cited is Sunday.As to the Article 64 of the Turkish Commercial Code lays down

Alıntı: Madde 664 - Vadesi pazara veya diğer bir resmi tatil gününe rastlıyan poliçenin ödenmesi, ancak tatili takibeden ilk iş günü istenebilir

Alıntı: a bill of exchange which has a maturity date encountering on Sunday or another official holiday could merely be required for payment on the subsequent work day.

Therefore you should heed on this provision as well.Hope it helps.
