Maturity Periods
If an obligation or any obligation of one of the parties must be performed at the end of a certain period of time starting from the conclusion of the contract, the time of performance shall be determined as follows: 1. A period fixed in days shall expire on the last day of that period, without counting the day of the conclusion of the contract. A period determined as EIGHT or FIFTEEN days means not ONE or TWO WEEKS, but exactly EIGHT or FIFTEEN DAYS. 2. A period fixed in weeks shall expire on the day of the last week which corresponds by name to the day on which the contract was concluded. 3. A period determined as a month or as a time including more than one month, such as a year, semester and quarter of a year, shall expire on the day of the last month corresponding to the day of the month on which the contract was concluded. If there is no corresponding day in the last month, the period shall expire on the last day of that month. 4. Half a month is understood as a period of FIFTEEN DAYS. The expiry day of a period of one or more months and half months shall be determined by adding fifteen days to the last month. These rules also apply in cases where the time period starts to run from a moment other than the conclusion of the contract. The obligor is obliged to fulfill an obligation that must be fulfilled within a certain period of time before the expiration of that period
