BOTH DATES INCLUSIVE (BDI)
Also known as: bdi, both dates inclusive, inclusive dates
A chartering and contractual term indicating that both the commencement date and the expiration date are included when calculating the applicable time period.
Both Dates Inclusive (BDI) is commonly used in charter parties, shipping contracts, and commercial agreements to make it clear that the first and last dates of a specified period are both counted. This removes ambiguity when determining laydays, cancellation periods, payment deadlines, or contract validity. Using BDI helps prevent disputes over time calculations by ensuring all parties interpret the contractual period consistently.
