Bid deadline D-day calculator
The days you can actually work on a bid are fewer than the calendar shows. Pick the submission deadline and this counts the business days left — weekends and Korean public holidays, substitute holidays included, are excluded.
Deadline times vary by agency (10:00, 17:00, …) — always confirm the exact closing date and time in the notice itself.
Deadline confirmed? The next question is whether your documents actually meet the notice’s requirements.
