It is a single day on a calendar with one date, starting from midnight to midnight. This would be different from things like a working day, which would not be 24 hours, or a 24 hour period starting on one day and finishing on the next day.
If you mean that your last period started on the third then the next one would be due on the 29th IF it remains at a 26 day cycle. Cycles are not always exactly the same from month to month. Start counting the days from the first day of your period. Don't include the first day of the next one when it comes as that is day 1 of your next cycle.
