So how many diaries do you need!
The reason for the title is the number of diaries people seem to use. In our office, the main diary is MIGTurbo, however, colleagues also use Google, various Mobile phone diaries and even Outlook! Absolutely mind blowing when you consider how difficult it is keeping just a single calendar in sync with birthdays etc.
Personally, I have never used the Outlook Diary, nor a diary in my mobile phone, personal organiser or any one of the many web based freebies! I used to use an A4 diary, until I tired of replicating information into my primary electronic diary - the one within MIGTurbo that is. Fortunately I can access this from any mobile phone or browser with an internet connection so I am usually always where I should be when I should.
Fortunately, there is a technology that enables you to synchronise all your different diaries within in a single diary of your choice. iCalendar is a file-format that allows calendar items to be sent/received and used between different calendar programmes that support files with a .ics suffix .
So, now you know, if you’re ever asked how many diaries you need, your answer should be - only one!
