With this browser-based application, you can test if the given year is a common year. You can enter any calendar year as the input and get its status as the output. Additionally, you can check multiple years at once and get a list of results for each of them. Created by computer nerds from team Browserling.

This is a quick online utility checking a year's type to see if it's a common year or not. It checks the given year using the common year testing algorithm and displays the status of the year on the screen. The Gregorian calendar has two types of years – common years, which have 365 days and leap years, which have 366 days. Common years dominate the calendar and typically three out of four consecutive years are common years. A more precise formula for calculating common years is as follows: a year is a common year if it is not divisible by 4, and when divided by 100 it's also not divisible by 400 at the same time. Our program implements this formula as an algorithm and uses it to test the input years and display the results. You can enter multiple years as input as well, one per line, such as "2026", "2030", "2032" and the returned output statuses of each of them will look like this: "2026 is a common year.", "2030 is a common year.", "2032 is not a common year.". Timeabulous!

In this example, we load a list of years from 2022 to 2033 and check which ones are common years. The program tests every year and prints the status messages on the screen. Out of 12 years in the list, 9 are common years and 3 are leap years.
In this example, we pasted sixteen random years from 1900 to 2100 into the input text area and ran a parallel common-year-checker algorithm on them. In the output text area, individual test results for each year were printed and you can easily see which years have 365 days.
You can pass input to this tool via ?input query argument and it will automatically compute output. Here's how to type it in your browser's address bar. Click to try!
