英文提醒請假信

Just a kind reminder that I am going to take 20/6, 22/6 and 23/6 off. Application was submitted last month.
Thank you for your kind attention.

LAST MONTH - 怎會用 Present Perfect Tense ? 用 Past Tense!
I am writing to inform you that I already applied for the personal leave of 20/6, 22/6 and 23/6 respectively last month.
