2-6 MonthsHow is 6 Months Calculated in the UK?
When calculating "6 months from now" in UK legal and business contexts, calendar months are typically used rather than a fixed number of days.
Calendar Months vs Days
6 calendar months means moving the same date forward by 6 months:
- 15th January + 6 months = 15th July
- 31st August + 6 months = 28th/29th February (adjusted for shorter month)
- 30th November + 6 months = 30th May

| March | Mar, Apr, May, Jun, Jul, Aug | 184 |

UK Legal Interpretation
In UK law, "6 months" typically means 6 calendar months from the relevant date. Key points:
- Employment: Notice periods are calculated in calendar months from the date notice is given
- Tenancies: Break clauses and notice periods use calendar months
- HMRC: Tax deadlines use specific calendar dates, not "months from" calculations
- Courts: Legal time limits may specify "calendar months" or "clear days" - always check

Frequently Asked Questions
6 months from today is calculated by adding 6 calendar months to the current date. If today is the 15th of any month, 6 months from now will also be the 15th (unless that month has fewer days). Use the calculator above to get the exact date - it accounts for different month lengths and leap years automatically.
In UK employment law, 6 months notice is typically calculated as 6 calendar months from the date notice is given. For example, if you give notice on 15th March, your last working day would be 15th September. UK statutory notice periods range from 1 week (under 2 years service) to 12 weeks (12+ years service). Many contracts specify longer notice periods, particularly for senior roles.
Neither - 6 calendar months is NOT a fixed number of days. The actual number varies from 181 to 184 days depending on which months are included. February (28/29 days) and months with 30 or 31 days all affect the total. For legal purposes in the UK, "6 months" typically means 6 calendar months, not a specific number of days. If a contract specifies "180 days", that's different from "6 months".
Common UK 6-month periods include: employee probationary periods (typically 3-6 months), tenancy break clauses (often at the 6-month mark), driving licence validity for non-UK residents (6 months to exchange), passport validity requirements for travel (some countries require 6 months), and HMRC payment plans (typically 6-12 months). Employment tribunal claims must usually be filed within 3 months of dismissal. Always verify specific deadlines with official sources.
