Calculation
1. Time limits to which the associations shall adhere commence the day after they have received the relevant document.
2. Time limits to which other persons shall adhere commence four days after receipt of the document by the association responsible for for- warding it, except when the document is not also or solely sent to the person concerned or his legal representative. If the document was also or solely sent to the parties or their legal representatives, the time limit commences on the day after receipt of the document in question.
3. If the last day of the time limit coincides with a public holiday in the place of domicile of the person required to comply with the document by a certain deadline, the time limit will expire on the next day that is not a public holiday.
4. In all other cases, the provisions of the Swiss Code of Obligations apply to calculate the time limits.
