About Travel Day Count

Day counting is where trip admin goes wrong, because nights and days are different numbers: a 1 June to 14 June trip is 13 nights but 14 days if both ends count. Nights drive hotel bookings, days drive leave requests, visa limits and per-diem claims. Subtracting the days spent purely getting there and back leaves the figure that actually matters for planning what you will do.

Formulas

Span

Nights = return date − departure date, in whole days

Days

Days = nights + 1 when both end days count; days at destination = days − transit days

Worked example

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Visa, residency and tax day-counting rules define arrival and departure days differently and often use rolling windows. Confirm the exact rule with the relevant authority before relying on a count.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Should I count both the first and last day?

It depends on what the count is for. Leave requests, visa day limits and per-diem claims normally count both ends inclusively; hotel stays count nights, which is one fewer.

Why does the nights figure differ from the days figure?

A night sits between two days. Any inclusive span of n days contains n−1 nights, which is why a hotel confirmation and a leave form for the same trip legitimately show different numbers.

Does this handle visa day-count rules?

It gives the raw inclusive count, which is the basis most schemes use. Rolling-window rules such as 90 days in any 180 also require your earlier trips, so check the specific scheme.
