<p>The potential of Twitter in the dissemination of scientific
publications has raised considerable scholarly attention. However, timely
patterns of interaction with scientific publications on Twitter have not been
covered broadly so far. This study examines the dates of when scientific
publications are tweeted, focusing on weekdays and months. For that, data was
collected from Altmetric.com, comprising of 25,227,143 tweets spanning the
years 2012 to 2016. Next to inquiring general patterns of tweeting dates,
subsets of three different Western European countries, several North African
states, and South Africa were observed. In general, the highest number of
tweets can be observed on Thursdays, with decreasing activity towards the
weekend. Concerning months, most tweets can be found in November, with both
October and December following close by. January is the month of least
activity. Comparing countries, timely variations
in tweeting activity were found. The authors conclude that the reception of
scholarly publications on Twitter is following certain timely patterns, while
geographical as well as cultural backgrounds of tweeters may influence those.</p>
