Since Solomon refers to some of the building projects he had undertaken, he must have written Ecclesiastes after their completion and before his deflection from true worship.
Karena Salomo merujuk ke beberapa proyek pembangunan yang telah dirampungkannya, pastilah dia menulis buku Pengkhotbah setelah proyek - proyek itu selesai dan sebelum ia menyimpang dari ibadat sejati.
