my manager ask me to send him my leave plan for the new year.
it's correct to say:
My annual leave is as follow:
/ / to / /
Please follow the rules of written English:
- Start every new sentence with a capital letter.
- End every sentence with a single punctuation mark (full stop, question mark, exclamation mark).
I have made some changes to your post in red.
If your annual leave has been agreed, then "My annual leave is as follows: 11/6/13 to 10/7/13". However, if you are requesting those dates (your manager has called it your leave plan) then you should say something like "I would like to book annual leave from 11/6/13 to 10/7/13".
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
