Let's implement CLI for date conversion, English to Nepali (AD to BS), and Nepali to English (BS to AD).

An example of a CLI would be:

ad2bs 2023-04-29
# Output: 2080-01-16

bs2ad 2080-01-16
# Output: 2023-04-29

In our current date converter code, we are using different reference points of date. The reference points are 2000/01/01 BS with 1943/4/14 AD and 1944/01/01 AD with 2000/09/17 BS. They are used inside the code as they are hard-coded.

With this, the maintainability of the code gets difficult. So the solution is to use one reference point of date, 2000/01/01 BS with 1943/4/14 AD which should be easily changeable in the future.

Support Nepali months and weekdays strings for formatting.

Eg.
Months: Baishak, Jestha, ..., Chaitra
Week Days: Sunday, Monday, ..., Saturday

Run the following code

package main

import (
	"fmt"

	"github.com/opensource-nepal/go-nepali/dateConverter"
)

type AD struct {
	year  int
	month int
	day   int
}

func main() {
	ads := []AD{
		{2024, 6, 13},
		{2024, 6, 14},
	}
	for _, ad := range ads {
		bs, err := dateConverter.EnglishToNepali(ad.year, ad.month, ad.day)
		if err != nil {
			panic(err)
		}
		fmt.Printf("%v-%v-%v-AD\n", ad.year, ad.month, ad.day)
		fmt.Printf("%v-%v-%v-BS\n", bs[0], bs[1], bs[2])
		fmt.Printf("\n\n")
	}
}

and you'll get as output

2024-6-13-AD
2081-2-31-BS


2024-6-14-AD
2081-3-1-BS

Note that conversion of 2024-6-13-AD is correct while the next day is not! 2024-6-14-AD should be 2081-2-32-BS!

The current version for this project has been set to 1.19. Let's upgrade the go version to the latest.

Support Nepali months and weekdays strings for parsing.

Eg.
Months: Baishak, Jestha, ..., Chaitra
Week Days: Sunday, Monday, ..., Saturday

Remove the absolute imports from the source code.

Eg: https://github.com/orgs/opensource-nepal/go-nepali/dateConverter

Add support for GO like Parse and Format layouts (date and time format).

Eg.

const layout = "Jan 2, 2006 at 3:04pm (MST)"
tm, _ := time.Parse(layout, "Feb 4, 2014 at 6:05pm (PST)")
tm.Format("2006-02-01")

The current documentation is weak and do not covers all the features of nepalitime.
