We all use calendars for a wide range of reasons. Where did they come from and why were they created ? Do they use the same calendar all around the world ? Are we still using the same calendar they used centuries ago ? Did other cultures use different calendars ? If they have changed, why have they changed ? …
These questions and more will find answers through the links below. As well, you will find ways to create calendars, discover information about special features such as solstices and equinoxes and convert dates between different calendars.
Calendars provide the big picture in terms of how we arrange time, but we also need to understand time each day, how we measure it, why time zones are important and how some features, such as daylight savings, have come into existence. Do we measure time in the same way as in the past ? If not, why has this changed ?
