10 Most Popular National Days in August
Want to know which national days in August are the real heavy hitters? We’ve compiled a top 10 of the national days that perform best on Instagram.
Popularity is based on Instagram hashtag usage only — how often each holiday’s main hashtag was used on that platform. A hashtag trending on Instagram doesn’t guarantee the day will do well on other platforms too, but it does give a good sense of the day’s overall reach. The list is compiled by hand and may be incomplete, but every number and fact has been manually fact-checked by us (latest update: September 2026).
