On the Google Calendar page I can access via a web browser, I can click on:Settings cogwheel | Calendars | to the right of any calendar entry click Edit notifications.The help icon next to All-day event notifications: says:Event notifications tell you about an all-day event at a specified  time some number of days before it begins. For example, if youd like  to be alerted about an all-day event at 9 am the day before it occurs,  youd set a notification.However, IMHO there are several use cases where one would need to be notified during the same day about an all-day event. The classical scenario is birthdays. I don't want to know about them the day before, but during the same day, perhaps in the morning around 8:30, or perhaps in the afternoon after work hours around 7:00 PM, these are the times when I would like the notification to be sent out for such all-day events, not the day before.Is there a way to configure such behavior in Google calendar, and if not then why is it missing / why is it not possible to program such behavior into Google calendar?
All-day-event notification: how to get notified during event, on the same day?

OK, perhaps the help message had some issues, but now I see that when I go to a specific calendar's Settings | Edit notifications tab I have the opportunity to set the following under All-day event notifications: which would pertain to the selected calendar whose settings I would be configuring:Notification method: pop-up, e-mail, or SMSspecify 0 days before event to have the event reminder on the very same dayspecify the time (e.g. 6:30) you want to be notified about the eventYou can even set more than one notification of the same type for either all-day events or regular events, and can set as many plans to receive notifications as you want.
