Given this df:
date
0 2001-08-10
1 2002-08-31
2 2003-08-29
3 2006-06-21
4 2002-03-27
5 2003-07-14
6 2004-06-15
7 2003-08-14
8 2003-07-29
and, if it’s not already the case:
df["date"] = df["date"].astype("datetime64")
To show the count of dates by month:
df.groupby(df["date"].dt.month).count().plot(kind="bar")
.dt allows you to access the datetime properties.
Which will give you:
You can replace month by year, day, etc..
If you want to distinguish year and month for instance, just do:
df.groupby([df["date"].dt.year, df["date"].dt.month]).count().plot(kind="bar")
Which gives:
