Nth Weekday Calculator
Find dates such as the first Monday, third Friday or last Sunday of any month.
How to Use the Nth Weekday Calculator
This calculator finds calendar patterns such as the second Tuesday, third Monday or last Friday of a chosen month. It is useful for recurring meetings, billing dates, community events, maintenance schedules and reporting deadlines.
Example
Choose 2026, September, Monday and 3rd to find the third Monday in September 2026. You can also choose Last to find the final occurrence of a weekday in the month.
Factors That Affect the Result
Not every month contains a fifth occurrence of every weekday. Month length and the weekday on which the month begins determine whether a fifth Monday, Tuesday or other weekday exists.
Frequently Asked Questions
Can every month have a fifth weekday?
No. Some fifth occurrences do not exist.
Can I find the last Friday of a month?
Yes. Select Friday and Last.
Can I use future years?
Yes. Enter any valid year.
Understanding Nth Weekday Calculator Results
This tool is designed for a specific calendar or time-planning task, so the result depends on the exact dates, times and conventions entered. Review boundaries such as midnight, week starts, month lengths and schedule assumptions when they apply. For planning across time zones, daylight-saving transitions or organization-specific calendars, verify those rules separately rather than treating a simple elapsed-time result as universal.
Calculation Details and Edge Cases
Finding the nth weekday requires locating the requested weekday within a month and then advancing by seven-day intervals. A fifth occurrence does not exist in every month, so the calculator should return no valid date rather than rolling into the next month.
