Clean, minimal, and unmistakably JSON — this Light Mode tee highlights the quietly iconic:

{"date": "1970-01-01"}

A perfect nod to the beginning of Unix time, ideal for developers who wrestle with timestamps, off-by-one conversions, timezones, or backend APIs that refuse to behave.

Soft, breathable, and great for stand-ups, code reviews, planning sessions, or explaining that no, this doesn't mean someone was born in 1970.

  • 100% combed and ring-spun cotton (Heather colors contain polyester)
  • Fabric weight: 4.2 oz./yd.² (142 g/m²)
  • Pre-shrunk fabric
  • Side-seamed construction
  • Shoulder-to-shoulder taping
  • Blank product sourced from Nicaragua, Mexico, Honduras, or the US

Disclaimer: The fabric is slightly sheer and may appear see-through, especially in lighter colours or bright lighting.

Printed on demand — structured, lightweight, and timeless in its own way.

Part of the JSON collection, within Data, Markup & Patterns.

Available in Dark Mode and Light Mode.

Heads-up

Shipping costs vary by region, so it’s worth giving the delivery total at checkout a quick look before confirming your order. Some variants may show limited availability in certain locations—if fulfilment isn’t available in your region, our suppliers will try to ship globally from the nearest facility that can produce that specific item. When this happens, delivery costs may be higher than expected due to the increased distance.

We’re constantly reviewing suppliers and expanding fulfilment options, and new routes may open over time.
