How to calculate months between two dates in Golang 1.20
0In this video we are going to generate source code for the GoLang Program, How to calculate months between two dates using chatGPT.
After generating we will verify and run the generated code.
IMPORTANT NOTE on SOURCE CODE: only source code that are acceptable by the youtube description box will be displayed.
##############SOURCE CODE#########################
package main
import (
"fmt"
"time"
)
func main() {
// Dates to compare
date1 := time.Date(2022, time.April, 1, 0, 0, 0, 0, time.UTC)
date2 := time.Date(2023, time.May, 1, 0, 0, 0, 0, time.UTC)
// Compute difference between dates
diff := date2.Sub(date1)
// Convert difference to months
months := int(diff.Hours() / 24 / 30)
// Print result
fmt.Printf("There are %d months between %v and %v\n", months, date1, date2)
}
Below is the explanation for the program:
The program uses the time package to represent the two dates that we want to compare.
In this example, we're comparing April 1st, 2022 and January 1st, 2023.
The program then computes the difference between the two dates using the Sub method of the time.Time type.
The Sub method returns a time.Duration value representing the difference between two times.
We then convert the duration to months by dividing the number of hours in the duration by 24 (the number of hours in a day) and approximately 30 (the average number of days in a month).
We use the int function to convert the result to an integer.
Finally, we print the number of months using the fmt.Printf function.
You can modify the program to compare any two dates you want by changing the date1 and date2 variables.
Note that this method for converting duration to months is approximate and may not give exact results for all cases.
