Inspired by traditional postal postmarks, this series references time-zone markings once used in mail processing and record keeping. Rather than precise timestamps, postal systems often indicated broad time periods, such as morning, afternoon, or night, to record when an item entered circulation or was processed.

These time divisions reflect the rhythm of a day as understood by postal workflows, and are reinterpreted here as markers for everyday moments.

About the time divisions

The stamps are based on commonly used time segments, including Japanese-style time notation:

0–6（未明）

Late night to early dawn.
6–12（午前）

Morning hours.
12–18（午後）

Afternoon hours.
18–24（夜間）

Evening to night.
Circular Time Dial

A flexible time marker without fixed boundaries.

Use it to indicate approximate timing, duration, or a moment that doesn’t fit neatly into one segment.

About previous designs

You may also explore postmark number designs from earlier years here, each reflecting a slightly different rhythm of time.

Each rubber stamp is assembled by hand with care and attention. We hope this set adds sparks to your everyday journaling, mailing, and creative practice, inviting you to continue exploring new possibilities.
