Deadline calculator
Calculate standard SAR, other data-rights, FOI/FOISA and EIR response dates using the current calendar-month, working-day, identity and clarification rules.
Your request
Use the date the request was received where you know it. The result is guidance, not legal advice.
What kind of request did you make?
For an email this will usually be the day it arrived. Postal requests can be different from the date you sent them.
Checking GOV.UK bank holidays…
Scottish public authorities generally use Scotland's separate FOI legislation. UK-wide authorities based in Scotland can still fall under FOIA 2000.
A complexity/numerous-requests extension must be necessary and the organisation should tell you within the first month.
Leave this blank if the organisation is still waiting for your clarification.
Most individual-rights requests use the Article 12 one-month response rule. A valid extension can add up to two further months.
Leave blank if you have not yet provided it.
How the calculator treats each request
This is why one generic “number of days” field is no longer used.
SAR / DSAR
Calendar month
Corresponding date next month; shorter months use the final day. Necessary ID affects when the clock starts; qualifying clarification can pause it.
Other data rights
Calendar month
The same general one-month response rule applies to rights such as rectification, erasure, portability and objection, subject to the limits of each right.
FOI / FOISA
20 working days
FOIA 2000 and FOISA 2002 ordinarily use 20 working days, but they have different holiday definitions and review routes. FOIA also has a public-interest extension mechanism that FOISA does not.
EIR
20 / 40 working days
Both EIR 2004 and the Scottish EIRs can reach 40 working days for a qualifying complex and voluminous request. A genuinely unclear request can start a fresh response period once sufficient clarification is received.
