You can add an event taking place over a period, with a start date and an end date, and/or single dates:
► Event with a single date, and a start time
eg a concert that starts at 20:00 and takes place only the selected day.
► Event with several dates, consecutive or otherwise, with a start time, which may be different for each date.
eg a concert that would take place a week on Friday and Saturday, and the following week on Friday. This concert can started at different times, and you can add new dates at any time.
Event over a Period
► Event over a period (from ... to ...).
eg a music festival which starts on Thursday at 14:00 and ends on Sunday at 23:00. In this case, you enter the start date and end date.
Event over a Period & Single Dates
► The event takes place over a period and you want to add specific hours.
eg A band participates in a music festival from Thursday 14:00 to Sunday 23:00. On Thursday, the band plays at 16:30, Saturday at 18:00 and Sunday at 13:15. You can then enter the period of the event (from Thursday 14:00 to Sunday 23:00) and add the single dates with time, when the band is on stage.
► The event takes place over a period, and other dates that are not in this period.
eg an event which takes place from Monday to Sunday (dates over a period) and another week on Tuesday and Friday (single dates).
