Thanks for asking Nick. Usually we award Photo of the Month between 20th-25th of the next month. If our team decided to announce a Photo of the Month before that deadline, we would always email all the participate of that month about the upcoming announcement date. You can also check our upcoming photo of the month section. The announcement date is also mentioned in each of the upcoming photo of the month page.
