Can I add or subtract days from a date?

Yes. Choose Add days, enter a start date and a number, then choose whether to add or subtract calendar days, weekdays, business days, weeks or months.

How are working days estimated?

Working days are estimated by counting Monday to Friday and subtracting the selected UK bank holidays plus any custom non-working days you enter.

Does this handle time zones?

No. These tools use plain calendar dates and simple durations for planning. They are not a time-zone, payroll or legal deadline calculator.

About date planning

Admin

These tools use plain calendar dates and simple durations, so they are best for planning, scheduling and admin estimates.

For formal deadlines, payroll, contracts or compliance, check the exact rules that apply to your situation.

UK date calculator and time span converter

Use these date and time tools to add days to a date, subtract days, count the days between two dates, estimate working days between dates, find deadlines, calculate age or time since, generate recurring dates and convert hours, minutes, days and weeks for planning.

Working day and business day estimates can exclude UK bank holidays for England & Wales, Scotland or Northern Ireland. Extra non-working days can be entered in DD-MM-YYYY format for annual leave, office closures or local holidays.

How to use the date tools

Choose the mode that matches the question you are asking. Add days when you need a date in the future or past, date difference when you want to count the gap between two dates, working days when weekends and bank holidays matter, and recurring dates when you need a simple schedule. The result card gives the answer, while the steps explain what was counted or excluded.

Calendar-day calculations count every day. Weekday calculations usually count Monday to Friday. Working-day calculations go a step further by removing selected UK bank holidays and any custom non-working days you enter. That distinction is important because "14 days from today" and "14 working days from today" can land on very different dates.

Examples of date planning

If a document is due 10 working days after a start date, choose the working-day mode, select the relevant UK nation and enter the start date. If a project milestone is simply 6 weeks away, calendar weeks may be more appropriate. If you are comparing two periods, the date difference mode can show the total span in days and make the period easier to explain.

The age and time-since modes are useful for everyday checks such as how long ago something happened, how old someone is on a particular date, or how many months sit between two dates. Month differences can be less intuitive than day differences because months have different lengths, so the calculator shows the method in plain language.

Important limitations

This page is intended for planning, scheduling and admin estimates. It does not replace legal deadline rules, payroll cut-off rules, court rules, contract wording or specialist compliance checks. Some formal deadlines treat weekends, bank holidays, time of day and service rules differently.

The tools use plain dates rather than time zones. That keeps everyday planning simple, but it means they are not designed for international time-zone conversion, daylight-saving edge cases or timestamp-based systems. For those situations, use the exact rules or software required by the organisation involved.
