How the dates are calculated. Deadlines are counted in calendar days from election day, from the day the elections are called, or from the day the voter register closes - exactly as in the law. Dates are not moved when they fall on a weekend or a public holiday, because neither ZINP nor ZJBS provides for that.
Why some deadlines have no date. More than half of the statutory deadlines do not run from the calendar but from an event - 48 hours from the submission of an electoral list, 72 hours from a decision being published. Those cannot be pinned to a date in advance, so they are shown as the rule that applies. ZINP is the Law on the Election of Members of Parliament; ZJBS is the Law on the Unified Voter Register.
Why a date can be one day off what you would count yourself. For deadlines that run backwards, the date shown is the last full day on which the act can still be done, not the day named in the law. Where the law says "no later than 20 days before election day", the calendar shows day 21. Deadlines set in hours are converted the same way: "72 hours before election day" becomes the fourth day before it. Deadlines that run forwards are counted plainly, with no day added.
