Custom Printed Calendars.

With a verification stage separate from normal proofreading — because date grids are exactly the kind of content the eye skims over.

A calendar with one day of the week misaligned, a missing public holiday, or a leap year handled wrongly is not a flawed product. It is scrap. There is no partial recovery and no way to correct it after printing.

What we recommend checking, deliberately and separately from approving the design:

• The first and last day of the year, and that they fall on the right weekdays.
• Each month's starting day independently. Do not check the first two and assume the rest follow — that is exactly how errors survive.
• Leap years, if February is involved.
• Any listed holidays against a current authoritative source, not against last year's artwork file. Dates move, and reusing an old file is the single most common source of errors.

We will supply a proof specifically for date checking. It is worth having someone who did not build the artwork do that check — a fresh pair of eyes catches what the designer's does not.
