What Is a Specific Day Finder?

This is a quick online utility for generating a specific calendar date that matches your criteria. For example, you can find all Fridays the 13th that fall in the same year, or you can find when the New Year falls on a Saturday, or you can print all Mondays in September. Our program can find the matching dates within one year (such as year 2025) or any custom date interval (such as all years from 2025 to 2035). You can enter the start and end dates for the search in the "YYYY-MM-DD" format in the options. For example, if the start date is 2000-01-01 and the end date is 2050-01-01, then the program will generate all specific dates from the first half of the 21st century. The search can be narrowed down by specifying the day, month, and day of the week. The day can be entered in the options as a number from 1 to 31. If this field is left empty, then any day will be used. The month and day of the week can be selected from a list. For example, you can choose that the month is only "February" and that day of the week is only "Wednesday". You can also set them to "Any Month" and "Any Day of Week". When specifying the date components you are interested in, you can choose just one of them, or choose two, or specify all three, which will find the most specific date possible. For example, you can specify that the day must equal to "12" and allow any month and day of the week. In this case, the program will generate every 12th day of each month as the output. If you specify the month as "June" and skip the day and weekday, then the tool will generate the June calendar with all days of June. If you set the day of the week to "Thursday", then our algorithm will find all Thursdays in all months. If you set the day to "12" and the month to "June", then you'll get all June 12th dates (one from each year in the search range). If you specify the day to be "12" and the day of the week to be "Thursday", then the search results will contain all Thursdays that fall on the 12th calendar day of the month (such as "May 12, 2022"). If you select the month "June" and the day of the week "Thursday", you will get the dates of all Thursdays in June. And if you specify all three components: the day "12", the month "June", and the weekday "Thursday", then you'll get only Thursdays that fall on the 12th of June of any year, such as "Thu, Jun 12, 2025", "Thu, Jun 12, 2031", and "Thu, Jun 12, 2036 ". The search result output can be tailored to your needs – you can display the calendar dates in numeric or textual formats and create custom date templates by switching to the custom mode in the predefined format list. When creating a custom date template, use the date format specifiers "YYYY", "MMM", "MM", "DD", and others. You can also control the zero-padding in dates (make years be four digits long and make months and days be two digits long), and customize the delimiter symbol that is printed between the generated dates. Timeabulous!

Find All Mondays in 2025

In this example, we print all Mondays in the year 2025. To get the result, we select "Monday" as the search day, "Any Month" as the search month, and we leave the day number empty, which makes our algorithm loop through all days of every month. The output dates use a vertical line symbol as a delimiter and the date format has abbreviated month names.

February 29 on Saturday

In this example, we find a very rare calendar date, which is Saturday, February 29th. As you know, February 29th happens only once every four years and the probability that it also falls on Saturday is very small. To find at least some results, we set the search range to an entire century, and we find only three such dates.

Find Leap Years

This example calculates all leap years of the previous century. The condition for a leap year is that the day February 29th exists in that year. To do this calculation, we enter February as the search month and the day 29 as the search day. Note that the year 1900 is not a leap year. Can you figure out why that its? (You can find the answer in our separate leap year generator tool.)
