The best days of the week for events — and the time slots nobody wants

She had scheduled the programme for a Friday afternoon. The venue was cheaper, her own diary was quieter, and she assumed delegates would welcome an early start to the weekend. She was wrong on all three counts.

Attendance came in at 58% of registrations — the lowest of her career. Evaluation scores were below par. And two delegates had emailed to ask whether the next edition could be held on a different day.

Day and time are not trivial choices.

What the data says

Analysis of attendance rates and satisfaction scores across multiple years of business events in the Netherlands reveals a consistent pattern:

Tuesday and Thursday are the best days for business events. Average attendance is 15–20% higher than on Monday or Friday. Delegates have no travel day at the start or end of the week, and no weekend-extension considerations to weigh up.

Wednesday performs well for half-day events but less so for multi-day gatherings — people are reluctant to block out an entire working week.

Monday has the highest no-show rate. People who wake up on a Monday morning facing a busy week ahead are most likely to cancel an event they could have withdrawn from the previous week.

Friday produces the lowest satisfaction scores for afternoon programmes. Delegates have mentally already begun their weekend.

Time of day

09:00–17:00 is the ideal window for a full-day programme. Starting earlier increases no-shows. Finishing later increases early departures.

10:00 is the optimum start time for a half-day morning programme. Delegates have had time to deal with their morning routine without the day already feeling pressured.

13:30–14:00 is the worst slot for content-heavy sessions. The post-lunch dip is measurable in both attention levels and active participation.

Drinks receptions score best when they begin at 16:30–17:00 and finish by 18:30–19:00. A later end time results in fewer delegates staying for the full programme.

Season and competition

September–November is the busiest season. Events compete with dozens of other gatherings for the same diary slots. Attendance is not necessarily lower, but the threshold for registering is higher.

January–February is the quietest season for business events. Venues are cheaper, diary competition is lower, and delegates arrive refreshed after the festive period.

April–May scores well for outdoor venues and team-building activities. The weather tends to be favourable and people feel motivated after a long winter.

What venue costs reveal about timing

The day rate at a popular conference venue can vary by 20–35% depending on day and season. A Thursday in October costs more than a Tuesday in February. That price difference reflects market demand — and market demand reflects when people actually want to attend.

Choosing the cheaper time slot also means choosing lower attendance and lower satisfaction. That is rarely a favourable trade-off.

The lesson

The event manager scheduled her next event for a Thursday at 09:30. "Not my ideal day," she says. "But the day that works for my delegates." Attendance reached 82% — her best result in five years.

She had learned the lesson that takes many organisers far too long to grasp: the event exists for the delegates, not for the organiser.
