About this tool
Generate an out-of-office auto-reply with exact dates, working days away, return date, backup contact and escalation path.
This generator writes an out-of-office auto-reply from your absence dates and turns those dates into the numbers people actually need: how many working days you are away, and the first Monday-to-Friday date you are back. Weekends are excluded automatically and any public holidays you list are removed from the count and skipped when picking the return date. It covers the four things a good auto-reply must state — the exact range, whether you are reading email, who to contact instead, and when a reply will arrive.

The first working day after your last day off is calculated for you, skipping weekends and listed holidays.
Absences over three working days flag a missing delegate, because 'I will reply on my return' is not a handover.
A character count warns when the reply grows past 500 characters and stops fitting a phone preview.
Four things: the exact first and last day you are away, whether you are checking email, who to contact for anything urgent with their email address, and the date you will start replying again. Anything beyond that — the reason, your itinerary, personal details — is optional and usually better left out.
Only if it helps the sender set expectations, such as business travel or a conference. Leave out medical, family or personal reasons: an auto-reply goes to every sender including strangers and mailing lists, and the reason rarely changes what they do next.
Use the first working day you are genuinely back at your desk, not the day you land or the weekend day your leave technically ends. If your last day off is a Friday, the return date is the following Monday — and a public holiday pushes it further.
Gmail and Outlook both let you limit the reply to your contacts or to internal colleagues only. Restrict external replies if your inbox receives client or confidential mail, since an auto-reply confirms a live address and reveals that you are away.
