60 Day Calculator

Q: How many weeks is 60 days?

60 days is 8 weeks and 4 days . That comes from 8 × 7 = 56, plus 4 leftover days. Because of those 4 extra days, the end date lands on a different weekday than the start date. If you start on a Monday, day 60 falls on a Friday.

Q: How many hours are in 60 days?

60 days equals: 1,440 hours (60 × 24) 86,400 minutes (60 × 1,440) 5,184,000 seconds (60 × 86,400) Fun fact: the number of hours in 60 days is the same as the number of minutes in one day.

Q: What happens if the 60th day falls on a weekend or holiday?

Most courts, banks, and offices push the deadline to the next business day . So if day 60 is a Saturday, your real due date is the following Monday. This rule is common but not automatic. Check your contract or court rules, because a few deadlines stay fixed no matter what day they land on.

Q: Do you count the first day when counting 60 days?

No. The standard rule is to skip the first day and count the last day . The day of the event is day zero, and the next day is day 1. Example: if a notice is served on March 1, then March 2 is day 1 and day 60 is April 30.

Q: How many business days are in 60 calendar days?

Between 42 and 44 business days , usually 43. A 60 day span holds 8 full weeks plus 4 days, so it contains 16 to 18 weekend days. The exact number depends on the weekday you start on. Holidays are not removed, so subtract those yourself if your deadline skips them.

Q: Which days count as business days?

Business days are Monday through Friday . Saturday and Sunday never count. Many contracts also skip public holidays like New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas. Some rules count only bank holidays, others count only federal ones, so check the wording before you count.

Q: When is a net 60 invoice due?

Net 60 means the full payment is due 60 calendar days after the invoice date , not the delivery date. An invoice dated March 1 is due April 30. Weekends count, so a due date can land on a Saturday. Many businesses pay on the next work day, but late fees may still start on day 61.

Q: Does a 60 day notice to move out start the day I give it?

Counting normally starts the day after the landlord receives the notice. If you mail it, some states add extra days for delivery. Many leases also require the 60 days to end on the last day of a rent period. That means a notice given on March 10 may push your move-out to May 31 instead of May 9. Read your lease before you pick a date.

60 Day Calculator

Introduction

The 60 Day Calculator tells you the exact date 60 days from any day you pick. Choose a start date and the answer appears right away, along with the day of the week it lands on.

You can also change the number of days. Add or subtract 30, 60, 90, 120, or any number you type. If you only want work days, check the box to skip every Saturday and Sunday. The start date is never counted as day 1, so counting begins the next day.

The second tab works the other way. Put in two dates, and it counts the days between them. You get the total in days, weeks, months, hours, minutes, and seconds.

People use this tool for court deadlines, rent notices, return windows, loan due dates, medical follow-ups, and school projects. Every answer comes with a step-by-step solution, five date formats you can copy, and a chart showing how many days are weekdays and how many are weekend days.

What Is 60 Days From Today?

Sixty days is about two months. When you count 60 days from a date, you start counting on the next day, not the day you pick. So if you start on September 17, 2026, day 1 is September 18, and day 60 lands on November 16, 2026.

How Counting 60 Days Works

A 60 day count moves straight across the calendar. It does not care how long each month is. Some months have 30 days, some have 31, and February has 28 or 29. That is why 60 days is not always the same as "two months." Two months from January 31 is different from 60 days after January 31.

Calendar days: every day counts, including Saturday and Sunday.
Business days: only Monday through Friday count. Weekends are skipped.

60 business days is much longer than 60 calendar days. Because each week has 5 work days, 60 business days is about 12 weeks, or around 84 calendar days.

Why People Count 60 Days

The 60 day mark shows up in real life more than you might think:

Rent and leases: many landlords ask for a 60 day notice before you move out.
Jobs: some contracts and benefit plans use a 60 day waiting period.
Bills and payments: "net 60" means payment is due 60 days after the invoice date.
Returns and warranties: stores often give a 30, 60, or 90 day window.
Health and fitness: lots of plans, workouts, and challenges run for 60 days.
Court and legal dates: many filing deadlines are set 60 days out.

Leap Years and Month Lengths

A leap year has 366 days instead of 365, and February gets a 29th day. Leap years happen every 4 years, but not in years divisible by 100 unless they are also divisible by 400. That is why 2000 was a leap year and 1900 was not. If your 60 day count crosses late February in a leap year, the end date shifts by one day.

Counting Backward

You can also go the other way. Counting 60 days before a date helps you find a deadline. If a notice is due 60 days before a move-out day, counting backward tells you the last day you can send it.

Quick Reference

Days	About How Long	As Business Days
30 days	1 month	about 22 work days
60 days	2 months	about 43 work days
90 days	3 months	about 64 work days
120 days	4 months	about 86 work days

A Tip Before You Count

Check how your contract or form defines a day. Some say calendar days, some say business days, and some skip public holidays too. This tool lets you choose whether weekends count, but it does not remove holidays. If holidays matter for your deadline, subtract them by hand or move to the next work day.

Frequently asked questions

How many weeks is 60 days?

60 days is 8 weeks and 4 days. That comes from 8 × 7 = 56, plus 4 leftover days.

Because of those 4 extra days, the end date lands on a different weekday than the start date. If you start on a Monday, day 60 falls on a Friday.

How many hours are in 60 days?

60 days equals:

1,440 hours (60 × 24)
86,400 minutes (60 × 1,440)
5,184,000 seconds (60 × 86,400)

Fun fact: the number of hours in 60 days is the same as the number of minutes in one day.

Is 60 days the same as two months?

Not always. Two months on the calendar can be anywhere from 59 to 62 days, depending on which months you cross.

January 1 to March 1 is only 59 days (60 in a leap year).
July 1 to September 1 is 62 days.

60 days always means 60 actual days. Two months means the same date number in a later month. Read your contract carefully, because the two rules can give different deadlines.

What does within 60 days mean on a contract or form?

It means you must act on or before the 60th day. Day 1 is usually the day after the event, and the 60th day is the last day you can act.

Acting on day 61 is late. Acting on day 30 is fine, since anything earlier still counts as within the window.

What happens if the 60th day falls on a weekend or holiday?

Most courts, banks, and offices push the deadline to the next business day. So if day 60 is a Saturday, your real due date is the following Monday.

This rule is common but not automatic. Check your contract or court rules, because a few deadlines stay fixed no matter what day they land on.

Do you count the first day when counting 60 days?

No. The standard rule is to skip the first day and count the last day. The day of the event is day zero, and the next day is day 1.

Example: if a notice is served on March 1, then March 2 is day 1 and day 60 is April 30.

How many business days are in 60 calendar days?

Between 42 and 44 business days, usually 43. A 60 day span holds 8 full weeks plus 4 days, so it contains 16 to 18 weekend days.

The exact number depends on the weekday you start on. Holidays are not removed, so subtract those yourself if your deadline skips them.

Which days count as business days?

Business days are Monday through Friday. Saturday and Sunday never count.

Many contracts also skip public holidays like New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas. Some rules count only bank holidays, others count only federal ones, so check the wording before you count.

When is a net 60 invoice due?

Net 60 means the full payment is due 60 calendar days after the invoice date, not the delivery date.

An invoice dated March 1 is due April 30. Weekends count, so a due date can land on a Saturday. Many businesses pay on the next work day, but late fees may still start on day 61.

Does a 60 day notice to move out start the day I give it?

Counting normally starts the day after the landlord receives the notice. If you mail it, some states add extra days for delivery.

Many leases also require the 60 days to end on the last day of a rent period. That means a notice given on March 10 may push your move-out to May 31 instead of May 9. Read your lease before you pick a date.

Does a 60 day return window start on the purchase date or the delivery date?

For in-store buys, the clock starts on the purchase date. For online orders, most stores start counting on the delivery date.

The receipt or order page usually shows the exact last day. Shipping time can eat into your window, so mail returns a few days early.

What is the 60 day rollover rule for retirement accounts?

If you take money out of an IRA or 401(k), you have 60 calendar days to put it into another retirement account. Miss that window and the IRS treats it as income, plus a possible 10% penalty if you are under 59½.

The count starts the day after you receive the money. Weekends and holidays count, and you can only do this kind of IRA rollover once every 12 months.

How do I count 60 days backward from a deadline?

Go back 2 months from the deadline, then adjust for month length. From a date in November, step back to September, then shift a day or two since September has 30 days and October has 31.

Example: 60 days before November 16 is September 17. Counting backward is how you find the last day to send a notice or file paperwork on time.
