How many months until September 1st 2023

Well, we already have dozens of date and time related calculators, including How many days are there between two dates? and How many weeks are between two dates?, but sometimes visitors ask in comments how many months are there between two dates. So, the calculator below should fill the gap. However, this can be a tricky question to answer, depending on how you understand the number of months in the difference, because, you see, the month is not a very definite unit of measurement.

So, this calculator follows certain convention, which looks just right for me. It counts full months taking into account days in the month. Here are a couple of examples.

• from 29th Jan to 1st Feb - 0 months 3 days [29, 30, 31 Jan]
• from 29th Jan to 28th Feb - 0 months 30 days [well, because it is not a full month]
• from 29th Jan to 1st Mar - 1 month 3 days [29, 30, 31 Jan]
• from 1st Feb to 1st Mar - 1 month 0 days
• from 1st Feb to 2nd Mar - 1 month 1 day [1st Mar]
• from 28th Feb to 2nd Apr - 1 month 2 days [28th Feb and 1st Apr]

That's it

Months between two dates

›› Date difference from May 11, 2020 to Sep 1, 2023

The total number of days between Monday, May 11th, 2020 and Friday, September 1st, 2023 is 1,208 days.

This is equal to 3 years, 3 months, and 21 days.

This does not include the end date, so it's accurate if you're measuring your age in days, or the total days between the start and end date. But if you want the duration of an event that includes both the starting date and the ending date, then it would actually be 1,209 days.

If you're counting workdays or weekends, there are 864 weekdays and 344 weekend days.

If you include the end date of Sep 1, 2023 which is a Friday, then there would be 865 weekdays and 344 weekend days including both the starting Monday and the ending Friday.

1,208 days is equal to 172 weeks and 4 days.

The total time span from 2020-05-11 to 2023-09-01 is 28,992 hours.

This is equivalent to 1,739,520 minutes.

You can also convert 1,208 days to 104,371,200 seconds.

This site provides an online date calculator to help you find the difference in the number of days between any two calendar dates. Simply enter the start and end date to calculate the duration of any event. You can also use this tool to determine how many days have passed since your birthday, or measure the amount of time until your baby's due date. The calculations use the Gregorian calendar, which was created in 1582 and later adopted in 1752 by Britain and the eastern part of what is now the United States. For best results, use dates after 1752 or verify any data if you are doing genealogy research. Historical calendars have many variations, including the ancient Roman calendar and the Julian calendar. Leap years are used to match the calendar year with the astronomical year. If you're trying to figure out the date that occurs in X days from today, switch to the Days From Now calculator instead.
