In a year, there are 52 weeks and one or two extra days, depending on leap years. Since 1 January was a Sunday, there will be 53 Sundays that year.

Every month has at least 28 days, which means they all have at least four Sundays. No month has six Sundays. So over the year, there must be 4 x 12 = 48 non-fifth Sundays.

That leaves 53 – 48 = 5 fifth Sundays. That means five parties celebrated in the year!
