In the post-Tanzimat Ottoman Empire context, the word was, in French, the main language of diplomacy and a common language among educated and among non-Muslim subjects, spelled as Cha'ban. The current Turkish spelling today is Şaban.
The Islamic calendar is a lunar calendar, and months begin when the first crescent of a new moon is sighted. Since the Islamic lunar calendar year is 11 to 12 days shorter than the solar year, Sha'ban migrates throughout the seasons. The estimated start and end dates for Sha'ban, based on the Umm al-Qura calendar of Saudi Arabia, are:
|AH||First day (CE/AD)||Last day (CE/AD)|
|1439||17 April 2018||15 May 2018|
|1440||6 April 2019||5 May 2019|
|1441||25 March 2020||23 April 2020|
|1442||14 March 2021||12 April 2021|
|1443||4 March 2022||1 April 2022|
