1. A computer-implemented method, comprising: electronically causing, via a computer network, by at least one specifically programmed computer processor of a schedule management computer system executing software to perform the method, to display a first specialized schedule graphical user interface (a first specialized schedule GUI) on a screen of each remotely distributed computing device associated with each user of a plurality of users; wherein the plurality of users are associated with a plurality of remotely distributed computing devices; wherein the first specialized schedule GUI is configured to allow each user to: i) define at least one programmed software schedule object, comprising a plurality of availability time periods (a plurality of TimeWindows), and ii) associate at least one programmed software schedule object with at least one of: 1) at least one user, 2) at least one resource, and 3) at least one service; wherein each TimeWindow is: i) defined by a plurality of TimeWindow parameters, and ii) configured to identify whether a corresponding time period is available for booking or unavailable for booking; wherein the plurality of TimeWindow parameters comprise: i) at least one first TimeWindow parameter, identifying a start date for the corresponding time period, ii) at least one second TimeWindow parameter, identifying a start time for the corresponding time period, iii) at least one third TimeWindow parameter, identifying an end time for the corresponding time period, iv) at least one fourth TimeWindow parameter, identifying at least one day of a week associated with the corresponding time period, and v) at least one fifth TimeWindow parameter, identifying a period type of the corresponding time period; executing, in real-time, by the at least one specifically programmed computer processor, a programmed software scheduling module which at least perform the following operations: electronically and in real-time, generating, based, at least in part, on the at least one fourth TimeWindow parameter, at least one first bitmask data object of days in a week for the corresponding time period of each TimeWindow of the plurality of TimeWindows so as to generate a plurality of first bitmask data objects for the plurality of TimeWindows, wherein the plurality of first bitmask data objects associated with the at least one programmed software schedule object; electronically and in real-time, storing a plurality of programmed software schedule objects associated with the plurality of users in at least one specifically dedicated database, wherein each programmed software schedule object comprises the plurality of first bitmask data objects; electronically causing, via the computer network, to display a second specialized schedule graphical user interface (a second specialized schedule GUI) on a screen of a remotely distributed computing device associated with a particular user, wherein the second specialized schedule GUI is configured to allow each user to submit an electronic query seeking to determine when a particular time period is available for booking or unavailable for booking, wherein the particular time period associated with at least one of: 1) the at least one user, 2) the at least one resource, and 3) the at least one service; electronically receiving, via the computer network, the electronic query of the particular user; electronically and in real-time, determining, based on the electronic query of the particular user, a set of TimeWindows selected from the plurality of programmed software schedule objects related to at least one of 1) the at least one user, 2) the at least one resource, and 3) the at least one service; electronically and in real-time, generating a union data structure of the set of TimeWindows, wherein the union data structure comprises at least one union data representation; electronically and in real-time, determining, based on each first bitmask data object of the plurality of first bitmask data objects associated with the set of TimeWindows, a second bitmask corresponding to the at least one union data representation; electronically and in real-time, determining an intersection data structure between the union data structure and the electronic query of the particular user to electronically identify at least one matched day of the week between the at least one union data representation and the particular time period identified in the electronic query of the particular user; electronically and in real-time, determining when the at least one matched day of the week includes the particular time period identified in the electronic query of the particular user, based, at least in part, on: 1) the at least one second TimeWindow parameter of a particular TimeWindow associated with the at least one matched day of the week; 2) the at least one third TimeWindow parameter of the particular TimeWindow associated with the at least one matched day of the week; 3) the at least one second TimeWindow parameter of the particular time period identified in the electronic query of the particular user; and 4) the at least one third TimeWindow parameter of the particular time period identified in the electronic query of the particular user; and electronically and in real-time causing at least one of: i) booking, by a respective remotely distributed computing device, the particular time period for the particular user when the at least one matched day of the week includes the particular time period identified in the electronic query of the particular user, wherein the respective remotely distributed computing device is associated with at least one of 1) the at least one user, 2) the at least one resource, and 3) the at least one service; and ii) generating an electronic scheduling alert on the screen of remotely distributed computing device associated with a particular user, wherein the electronic scheduling alert identifies that the particular time period is unavailable for booking when the at least one matched day of the week excludes the particular time period identified in the electronic query of the particular user.
