Cool usability features


One subscription fee – as many diaries as you like. Yes, really. One diary is automatically created for you. You add as many extra diaries as you want. (Pro version only)


Keep each diary private, or select which friends, family members or colleagues you’d like to share it with. Give them read-only access so they can see what you are up to, or grant them read-write access and they can contribute to your diary too.

Set up events quickly and easily

Choose a time and date and internetDiary will check all of your diaries and warn you of any conflicts. Select from a list those you’d like to invite and internetDiary will send them an email, or if you prefer, a text message.

Automatically send reminders

Select any time from 15 minutes to a week before the event and internetDiary will do the rest, sending each person a reminder by your preferred contact method. Never miss another appointment or forget someone’s birthday again.

Import your contacts

Easily import your contacts from Outlook or Outlook Express or manage your address book manually. internetDiary takes you through it step-by-step.


Organise your contacts into groups – contact every person in a group with a couple of mouse clicks.

About Us

Diary UK Limited was formed in March 2004 by Steve Webb and Ray McGinty after they failed to find any existing software which would do exactly what they wanted. They were looking for a diary service they could access anywhere, which could keep all of their contacts in one place and would allow others to view or edit their schedule.

They had used Lotus Notes and Microsoft Outlook before, but were frustrated by their complexity, and the fact that they couldn’t be accessed when away from the company network. They wanted something which would give them the same functionality, or better, with a more intuitive interface, that would work from any internet connected device anywhere in the world.

They searched long and hard, and tried many online services, but none they found were up to the mark. So they decided to build their own! The result is internetDiary.
