For the Aday.org project we ask you take pictures on May 15. We all know that a day has 24 hours, but balancing on the international dateline, May 15 will last 48 hours in total.
In the South Pacific, islands closest to the dateline are in some cases directly north or south of each other yet on different days. Kiribati (pronounced kirr-i-bas) has a population of about 100 000 and straddles the equator. The Cook Islands has a population of nearly 18 000. At just after midnight on Tuesday in Kiribati, it will be just after midnight on Monday in the nearby Cook Islands, almost directly south.
When photographers start clicking in Kiribati early on Tuesday, Cook Islanders will still have 24 hours to puzzle, ponder and prepare.
So remember: The upload site will open as soon as the first time zone hits May 15, but it is important that you to take photos only during the 24 hours when it is Tuesday, May 15, where you live.
