You have to use this function as a filter function. Means you cannot use it directly in a measure.
#Last leap year code#
The code above returns a table with one single column: date. this is how you can get this function working: SAMEPERIODLASTYEAR(DimDate.) The SamePeriodLastYear function like many other time intelligence functions needs a date field to work. The image below shows how the SamePeriodLastYear works for Date You can use the function simply just by providing a date field: If you are slicing and dicing in a month or quarter level this would give you the same month or quarter last year.
Let’s start with the SamePeriodLastYear function this function will give you exactly what it explains same PERIOD but last year! same period means if you are looking at data on the day level, it would be same day last year.

Let’s take a look at these questions and their responses in more details through this post. and many other questions that lead to this final question: Which function should be used in which situation?.ParallelPeriod for a month vs DateAdd for a month ago.SamePeriodLastYear function vs using ParallelPeriod with Year parameter.It was thought there could be a leap second added in June 2022, but according to Time and Date, that won't happen and the next time it could is December 2022.Using DAX time intelligence functions for a while you may ask this question from yourself that what is the difference between functions below The last leap second was added on December 31, 2016. Occasionally, a second is added to the year's calendar to make up for slight differences between orbit time and the length of a year, even with leap years added to the calendar. The Royal Observatory says "Because the Earth takes a little over 365 days to orbit the Sun, we need to make adjustments to keep the seasons from drifting: leap years and even leap seconds." What's a leap second? 4 x 6 = 24, and there are 24 hours in a day. So, in a four-year cycle, we have three years of 365 days, and then one year with 366 days, to take into account the extra six hours it takes for the earth to orbit the Sun. To make up for this, those six hours are added together every four years to make a 29th day in February. That orbit takes approximately 365 days and six hours, which means there are six extra hours left over each year. It adds: "2020, 20 are all leap years." Why are there leap years?Ī year is measured in the time it takes the earth to orbit the sun. This means that the year 2000 was a leap year, although 1900 was not." The Royal Observatory explains : "To be a leap year, the year number must be divisible by four – except for end-of-century years, which must be divisible by 400. To be a leap year, the year number must be divisible by four.
That means the next one will be February 29, 2024, as they are four years apart. The last leap year was February 29, 2020. Most choose to mark their celebrations on February 28 or March 1 when it is not a leap year. Traditionally, February 29 is a day where women propose marriage to male partners, not that there is anything wrong with proposing to a man on any other day of the year.įebruary 29 births create an interesting situation, as they only get to celebrate on their actual birthday every four years. The next leap year is not for two years yet. Read more: Where to get pancakes in Newcastle for Pancake Day Tuesday will be the beginning of March, Monday is the final day of February in 2022. This year is not a leap year, the last one was in 2020. Leap years mean an extra day in February every four years.Īn additional day is tagged onto February, giving it 29 days, as an adjustment to make up for it taking a little bit over 365 days for the earth to orbit the sun, so every four years the year has 366 days.
