To forget nothing of the planned, in time to remember the necessary business and just to organize the working day is very convenient to use the calendar to schedule. And if your working day runs behind a computer screen, it is logical to use a calendar, scheduler, eg mozilla Sunbird.
It is fully cross-platform program, free, works on all common platforms and has a localized interface. Calendar functions is, actually, a calendar, a task scheduler for each day, indicating exact start and end times, a warning for some time prior to (as a sound signal, and mail). All events and tasks can be grouped by category (there are several dozen preset), set up the repetition. You can create and group events, inviting other participants. As such Sunbird can be used as a simple application for managing projects (in the case of using a server for joint calendars supported iCalendar and CalDAV server). The program supports and interchangeable themes, and custom extensions, because built on the same basis as the Firefox browser and Thunderbird e-mail client. In addition to the regular program, Sunbird is also in the form of extensions with Thunderbird, this form it is called Lightning. It appeared panel "Events", which allows to immediately assess all the upcoming events and tasks. But integration with the Firefox browser still in development.
Of course, by itself calendar scheduler does not organize your time, but if you decide to use Sunbird, the process will be simple and beautiful, but still free. By the way, do not forget to import a list of various holidays and anniversaries for your country, and now you never miss a day, a sign language interpreter on October 31 and November 17 of the precinct to congratulate you on your professional holiday How? Of course, on the Day of the precinct!
