When I go through my emails or twitter/LinkedIn feeds I don’t have a calendar with me. I guess I do but I’m too lazy to open it up. Noticeably, there are many brochures or announcements about upcoming events that don’t list the day of the week. For me, that’s a nuisance so I don’t even read the information.
When writing or posting an event always put the day of the week along with the date. For instance; instead of putting June 12 & 13 write Tuesday and Wednesday, June 12 & 13. You can abbreviate Tues. & Wed. You just might see the attendance increase for your event.
