With this browser-based application, you can find the average date of multiple calendar dates. You can calculate the middle point between two dates, or the average of three, four, or more dates. The program will find the average value as accurately as possible, up to a second. You also can calculate the running average for multiple dates, and change the calendar format for the average date in the output. Created by computer nerds from team Browserling.

This is a quick online utility for calculating the average of two or more calendar dates. For example, you can find which day is the mid-spring by entering two dates: the beginning of spring (March 1) and the end of spring (May 31). The answer is noon on April 15. In a similar way, you can find the middle of a month, quarter, year, or century. You can also find the average of three or more calendar dates. Each date must be written on a new line using the format "YYYY-MM-DD hh:mm:ss" or "YYYY-MM-DD". For example, good inputs are: "2020-01-04 12:00:00" and "2030-10-23". The program then runs through the dates and calculates the average date using the formula "average = (d₁ + d₂ + … + dₙ)÷n", and displays the result in the output. You can also turn on the moving average mode (also known as rolling average and running average) in the options and get a list of sequential average date calculations as the output. Additionally, you can choose a format for the average date from a list of formats in the options or create a custom format using a pattern with the special date component abbreviations (such as YYYY, MM, DD, hh, mm, ss, and others). Two more options let you change the clock time format (switch between 12-hr and 24-hr modes) and add or remove zero padding to all date and time components. Timeabulous!

In this example, we calculate the average of two calendar dates. To do this, we enter both dates formatted as "YYYY-MM-DD hh:mm:ss" to the input (one per line). Then we set the output date format to be the same as the input date format and get the middle point between the two dates as the result.
In this example, we find the rolling average of three dates. We switch the output date format to text format with a 12-hour clock time and abbreviated month and day of the week names. On the first line of output, the program displays the same 1st date (because the average of just one date is the same date). On the second line, the program prints the average of the 1st and 2nd dates. On the third line, the program returns the average of the 1st, 2nd, and 3rd dates.
In this example, we find the average of two calendar dates without the time part. We discard the clock time from the output date by using a custom average date format. To do this, we select the "Custom" format mode in the list of formats and enter the date pattern YYYY_MM_DD, which separates the year, month, and day by an underscore symbol.
In this example, we calculate the date and time of the middle point of a regular year, which has 365 days. The beginning of the year is 2023-01-01 00:00:00 and the end of the year is 2023-12-31 23:59:59. In the output, we get the midpoint of the year, which occurs in the summer of 2023-07-02 at exactly 12:00:00.
In this example, we find the median of the leap year 2024. This year consists of 366 days, which has one more day than a common year of 365 days. Because of this extra day, the midpoint of a leap year, as compared to a common year, is shifted by 12 hours, and is midnight of 2024-07-02.
This example finds the midpoint of the entire 21st century. The current century runs from "2000-01-01 00:00:00" to "2099-12-31 23:59:59" and has one hundred years in it. We paste the beginning and end dates of the century into the input and find that the middle of the 21st century equals "2049-12-31 12:00:00".
