💡 Did you know? Many real-world schedules use the "2nd Tuesday" pattern: Microsoft Patch Tuesday releases on the 2nd Tuesday of each month. Many board meetings are scheduled this way. Cron jobs and calendar applications can express most recurring patterns, but "Nth weekday" patterns like "2nd Tuesday" require special handling.
Frequently Asked Questions
Here are all 12 dates for the Last day of the month in 2020. The next occurrence after today depends on the current month. Check the table below for the full list.
A recurring date is one that repeats on a regular schedule: monthly, weekly, quarterly, etc. Examples: monthly billing on the 1st, payroll on the 15th and last day of the month, board meetings on the 2nd Tuesday of each month.
Start with the 1st of the month, advance 7 days, then walk forward until you hit a Tuesday. This gives the 2nd Tuesday. Our calculator uses this same algorithm. 3rd Wednesday = start + 14 days, then walk to Wednesday. 4th Thursday = start + 21 days, walk to Thursday. Last Friday = last day of month, walk backward to Friday.
The last Friday of the month varies: it falls on the 1st through 7th of the month. Our calculator finds it by starting at the last day of the month and walking backward to the previous Friday.
The '2nd Tuesday rule' is famous in US election law: federal elections are held on the first Tuesday after the first Monday in November (which is the 2nd Tuesday in most years, but the 1st Tuesday in years where November 1 is a Tuesday).
Common patterns: (1) Fixed day, like the 15th. (2) Last day of month for billing. (3) Nth weekday, like '2nd Tuesday' for board meetings. (4) First weekday, like '1st Monday' for rent payment. Our calculator handles all four.
Cron expressions support recurring patterns: '0 0 1 * *' = 1st of month at midnight, '0 9 * * 1' = every Monday at 9 AM, '0 0 15 * *' = 15th of month. For '2nd Tuesday' patterns, cron doesn't directly support it; use a wrapper script.
A year has either 52 or 53 Tuesdays. There are 53 Tuesdays in a year if Jan 1 is a Tuesday, or if it's a leap year and Jan 1 is a Wednesday. Examples: 2025 has 53 Tuesdays, 2026 has 52 Tuesdays.
