plot count of events against months from large dataset

and I have got a column
showing the year-month-day of the event as follows:

df = read.table(text = 'ID Date
1 1975-10-01
1 1975-10-04
2 1975-11-03
2 1976-01-17
2 1980-02-04
3 1980-05-11
4 1983-03-09
4 1983-04-10', header = TRUE)

df$month <- factor(lubridate::month(df$Date), 1:12,

ggplot(df, aes(month)) + geom_bar() + xlim(
