Mothers' Day special program with artist Bitsat Seyum. A calendar is a tool that helps us keep track of time. It tells us what day, month, and year it is. We use calendars for various reasons such as planning events, religious holidays, work schedules, and business meetings. 

It lets people plan and manage their to-do lists and write down their daily experiences for a certain period. We give names to certain periods, like days, weeks, months, and years. A date is the name of a day. 

The calendar uses the sun or the moon to measure years and months. Lots of different groups of people have made their calendars, based on other calendars they know about. They make them fit the specific things they need.

There are many different ways to make calendars. Some calendars are based on the sun, moon, and stars, while others just repeat the same pattern over and over. The calendars that use the sun and moon to make them are very famous.

A solar calendar is a type of calendar that shows which position the Earth is in as it goes around the sun. A solar calendar gives a specific day a certain date. A day can be the time from when the sun comes up until it goes down, and then the time from when it goes down until the sun comes up again.  

The time between two events can change a little bit throughout the year, or it can be averaged to create an average solar day. Solar calendars have either 365 or 366 days in a year, depending on whether it's a leap year or not.
