1 day leave application mail for personal reason

Here is a sample email for a 1-day leave application for a personal reason:

Subject: Request for One-Day Leave on [Date]

Dear [Manager's Name],

I am writing to request a one-day leave on [Date] for personal reasons. Unfortunately, I have a personal matter that requires my attention on this day and I will be unable to come to work.

I apologize for any inconvenience this may cause and will ensure that all my tasks are completed before taking the leave. I will also be available by email if anything urgent comes up while I am away.

I would greatly appreciate it if you could approve my request.

Thank you for your understanding and I look forward to hearing back from you soon.

Best regards,

[Your Name]
