As more people are invited to take part in a doodle, then the chances of finding a date at which everyone is available goes down. Increasing the number of dates to choose from increases the chances. If each invitee-date has an independent probability, θ, of being available, there are k people, and n dates, then the probability of getting at least one suitable date is

<math>\{1- (1-\theta^k)^n\}</math>

Or equivalently, to ensure an overall chance of success greater than p, choose the number of potential dates to be greater than

<math>\log(1-p)/\log(1-\theta^k)</math>

RegistrationNot required

Doodle is an Internet calendar tool for time management, and coordinating meetings. It is based in Zurich, Switzerland and has been operational since 2007.

Users are polled to determine the best time and date to meet.[3] Meeting coordinators (administrators) receive e-mail alerts for votes and comments. Registration is required to have this function.[4]

Doodle interacts with various external calendaring systems, such as IBM Notes. Through the use of a widget for Lotus Notes, users are able to create and manage Doodle polls within a Lotus Notes client application. Google Calendar, Yahoo Calendar, Microsoft Outlook and Apple iCal can be utilized with Doodle to track dates. Google Maps may also be used to share the location of the event.[4]

Similar popular competing products, which may collectively be designated as "date matchers", include Dudle[5] (Free Software maintained by the TU Dresden),[6] ScheduleOnce, Tungle (which ceased 3 December 2012), TimeBridge, WhenIsGood, Framadate[7] or Xoyondo[8].
