It’s that time of the month again! The time when you get all your blogging, content-marketing, meme, and social media calendar ideas for the upcoming few weeks in one place.
So, without much preamble, let’s dive into this big list of exciting events, cool holidays, lively festivals, significant occasions, and quirky days coming up in September 2021 you can use for planning and timing your posts.
(A note: I’m excluding popular birthdays and death anniversaries from the list. I’ve realised it’s quite an exclusionary approach to spotlight just a few people for these. Besides, it’s very easy to miss out on a LOT of these dates.
I’m also skipping movie anniversaries this time. You have to admit that researching these dates for films across ALL languages in India and abroad is a labour-intensive effort for a time-starved solo blogger. At the same time, it’s difficult to verify these release dates if they vary across countries. Ditto for sporting events, which are subject to unexpected cancellations and rescheduling these days, so it becomes very cumbersome to update the calendar as and when.
Still, there’s quite a lot happening this month, so you have plenty to work with! Save and bookmark this September 2021 content calendar to make the most of it.)
