 ## Command Line
 
 The `nepcal` CLI was initially inspired from the `cal` command on Linux, but expanded to have much more functionality, namely:
 
-* [x] Show the current Nepali month's calendar (Similar to `cal`)
-* [x] Show today's Nepali date and day
-* [x] Convert A.D. (gregorian) dates to B.S. dates and vice-versa.
