📅 About This Countdown
This countdown uses calendar days rather than exact hours. The week-by-week table follows ISO calendar weeks, with Monday as the first day and Sunday as the last day.
If today falls after Monday, the current week is marked Current week (partial) because the countdown begins partway through that ISO week.
If the target date falls before Sunday, the final row is marked Final partial week because the countdown ends on the target date rather than continuing through the rest of Sunday.
