![]() I then plotted these results and found the resulting pie chart looks eerily similar to Pac- Man chasing and gobbling up hours (especially after adding the eye and yellow hour balls). I also calculated the number of business days (excluding federal holidays) remaining until my anticipated retirement at age 65 (Dec. 11, 1982) to the day I wrote this column as 9,064. For example, I calculated the number of business days (excluding federal holidays) from the day I started my professional career (Jan. The tool's power becomes more obvious when multiple years are involved. Keep in mind that some businesses give employees Friday or Monday off if the actual holiday is on a weekend, and Excel does not account for this. In case you are wondering why the total business days declined by only eight days from 260 to 252 when 10 holidays were subtracted, the reason is that two of those holidays fall on weekends and, therefore, were already excluded from the original calculation mention above. The formula is identical to the solution described above, except this time the 10 federal holidays are highlighted at the end of the formula, which reads as follows: =NETWORKDAYS(B3,B4,B6:B15).Īs you can see in the screenshot above, 2017 contains 252 total business days, excluding weekends and federal holidays. The example below depicts the start and end dates for the time period in question, along with a list of the 10 standard federal holidays, in cells B6 through B15. Excel cannot automatically determine whether these specific holidays or others are to be excluded from your calculation therefore, you must enter all holiday dates yourself.) 24, 2017, (the day after Thanksgiving) as a state holiday. As examples, the District of Columbia celebrates Emancipation Day on April 16, 2017, as a district holiday, and both Indiana and West Virginia celebrate Lincoln's Day (for Abraham Lincoln) on Nov. (You must type in the holiday dates you want to exclude because there are more than 200 official holidays, and Excel does not know which ones you want to exclude. Birthday Calculator Find when you are 1 billion seconds old. Date Calculator Add or subtract days, months, years. Time and Date Duration Calculate duration, with both date and time included. To apply this additional functionality, you must first type in all the specific holiday dates you want excluded. Duration Between Two Dates Calculates number of days. It is centurial and NOT divisible by 400 Is 2100 a leap year? No.You may also want to calculate the number of business days in a given period excluding holidays the NETWORKDAYS function can also perform this calculation. It is centurial and it is divisible by 400 Is 1900 a leap year? No. It is divisible by 4 Is 2000 a leap year? Yes. It is NOT divisible by 4 Is 2020 a leap year? Yes. It is NOT divisible by 4 Is 2019 a leap year? No. It is NOT divisible by 4 Is 2018 a leap year? No. It is divisible by 4 Is 2017 a leap year? No. In the Gregorian calendar there are only 365 days, therefore on leap years an extra day is added on February 29th to account for this quarter of a day deviation, which would otherwise lead to the calendar being out of sync with reality after not too long. It would be correct to say that ‘it takes the earth just less than 365.25 days to go around the sun’. But that is also wrong as this doesn’t account for the centuries that are not divisible by 400 and therefore not a leap year. It is fairly common for people to say there are actually 365 and a quarter days (365.25) in a year. Sometimes 52 weeks and 2 days (leap year).Ī leap year occurs every year that is divisible 4 with the exception of every century year not divisible by 400 Sometimes 52 weeks 1 day (non-leap year). Therefore there are always MORE than 52 weeks in a year. But I’ve always wondered why people say there are 52 weeks in a year.Īfter all, 52*7 is only 364 and we all know there are 365 days in a non-leap year and 366 days in a leap year. But since the Earth spins on it’s axis and we call one of those spins a day, then we can give a measurement in days and therefore weeks fairly accurately. Precise answer = 52.177457 weeks or Just under 52 weeks 1 day and 6 hours 52 weeks 1 day and just under 6 hoursġ year is the time it takes for the earth to go around the sun.
