The A to Z Challenge is posting every day in April except Sundays (we get those off for good behavior.) And since there are 26 days, that matches the 26 letters of the alphabet. On April 1, blog about something that begins with the letter “A.” April 2 is “B,” April 3 is “C,” and so on. You can use a theme for the month or go random – just as long as it matches the letter of the alphabet for the day. - See more here
At the last count there are 2160 bloggers taking part - big number!
