Therefore, finding how many months between dates does not require leap-year adjustments regardless of the time interval in question. Likewise, Feb 1 till Jul 31 is always six full months, regardless of leap years. For example, the time period between Mar 1 and is always 7 full months. Neither difference in number of days in each month, nor leap years play a role when calculating the number of full months between two exact dates. If calculating the number of months between two dates by hand, the following table can be useful for adjusting the count based on the number of days in any given month: Number of days in each month Month

Using a month counter means you need not worry about these complications. Some months have 30 days, others 31 days, and February has only 28 days in a typical year and 29 days in a leap year. What also makes it difficult is that different months have a different number of days. When calculating the number of months between dates separated by a longer period of time, leap year adjustments need to be considered or one can be off by a month or more in certain scenarios. How to calculate the number of months between dates The months calculator will return the number of full calendar months since, as well as the exact number of months and days since, while accounting for leap years. Similarly, if you are interested in the number of months since a given date in the past, just enter it in the 'Start Date' field and select the present date in the second. For example, if a work assignment has a deadline on Dec 21, 2024, simply enter the current date in the first field and and press the button to get an exact count of the number of full months in between, as well as exact duration in months and days. To use the tool, simply enter the start and the end date of the time period. A month counter can also be useful in analyses that require the calculation of the duration of past events with a known start and end date. For example, it can be used to estimate the number of months available to finish an assignment given some deadline, or to calculate the duration of a long trip or business travel assignment.

Unlike the date_create function, the setTimestamp method assumes the time zone of the server (CET in my case) rather than GMT. However, if I execute this code from a Belgian server, I get the following output : T14:17:52+01:00 You might expect this to produce the same output. Option 2 : date_create()->setTimestamp($timestamp)Ĭonsider the following code : date_format(date_create()->setTimestamp(strtotime('Mon, 21:17:52 +0800')), 'c') The strtotime bit eliminates the time zone information, and the date_create function assumes GMT.Īs such, the output will be the following, no matter which server I run it on : T13:17:52+00:00 While is correct to assert there are multiple ways to convert a time string to a datatime, it's important to realize that these different ways don't deal with timezones in the same way.Ĭonsider the following code : strtotime('Mon, 21:17:52 +0800')), 'c')
