You must act on the subject access request without undue delay and at the latest within one month of receipt.
You should calculate the time limit from the day after you receive the request (whether the day after is a working day or not) until the corresponding calendar date in the next month.
If this is not possible because the following month is shorter (and there is no corresponding calendar date), the date for response is the last day of the following month.
If the corresponding date falls on a weekend or a public holiday, you have until the next working day to respond.
This means that the exact number of days you have to comply with a request varies, depending on the month in which the request was made.
For practical purposes, if a consistent number of days is required (eg for operational or system purposes), it may be helpful to adopt a 28-day period to ensure compliance is always within a calendar month.
