Google Calendar users have been experiencing a bug that is creating random events with no explanation. The issue has been reported by various users on Twitter, who took to the social media platform to share screenshots of their Calendar apps filled with all-day events that do not correspond to any actual event. According to a report by 9to5Google, this is being caused by a bug in the Gmail mobile application on some Android and iOS devices. 

Google Calendar appears to be generating random created events triggered by messages in Gmail inboxes that don't necessarily track back to any real event. These incorrect events are mostly appearing as all-day events which suggest that the bug lies within the mobile application of Gmail itself. Some people have also noticed other issues such as incorrect dates or times associated with these randomly generated entries, while others are experiencing different kinds of bugs altogether such as duplicate entries or even blank calendar days where nothing shows up at all. 

Unfortunately, it isn't yet clear what particular bug has caused this issue but it would seem likely that an update within either the Gmail app or Google Calendar itself could potentially fix this problem for those affected by it. In addition, there's always the option of manually deleting these wrongfully generated entries from one's own personal calendar if they don't want them cluttering up their schedule anymore - something which may become necessary for more serious cases where multiple erroneous items keep reappearing despite attempts at deletion otherwise. 

All in all, this recent issue with Google Calendar should serve as a reminder for us all about how important it is for software developers and companies alike to constantly strive towards improving their products and keeping them up-to-date so as not to experience similar problems down the line - especially when considering how much we rely on technology nowadays!
