Why use WorldSmith's D&D calendar generator?

Tracking in-game time gets messy when you're juggling session notes, travel days, and long rests. This fantasy calendar generator creates a complete calendar system in seconds — month names, seasonal events, moon phases, and festival days — so you never lose track of your campaign timeline.

Most calendar tools are either too generic (Donjon's bare-bones form) or too complex (Fantasy-Calendar's premium features). WorldSmith gives you D&D-specific presets like Forgotten Realms and Greyhawk, plus full customization for homebrew worlds. Export to PDF, share with your table, or track session-by-session progress — built for how DMs actually run campaigns.

Max Farrick (The Con-Man)

⌄

A deception-focused rogue NPC with a full 5e stat block built for urban intrigue. Use him as a recurring trickster antagonist, a heist contact who double-crosses the party, or a CR 9 challenge in social-heavy campaigns.

Lord Verin (The BBEG)

⌄

A CR 15 tiefling villain with legendary actions, full spellcasting, and a political power structure behind him. Built for DMs who need a central antagonist with real mechanical depth and enough arc material to carry an entire campaign.

Adella Holt (The Master)

⌄

A CR 5 retired fighter NPC with battlefield history and a hidden guilt your players can uncover. Works as a mentor, trainer, or reluctant quest giver who hands out missions with real personal stakes attached.

Garrion Splint (The Launderer)

⌄

A CR 3 dragonborn merchant NPC with financial leverage and a network of front companies. Perfect for city campaigns, faction intrigue, and players who need a fixer with morals and secrets worth investigating.

Gorta Bibber (The Herbalist)

⌄

A CR 5 hill giant herbalist NPC with a gentle personality and a traumatic backstory. Built for wilderness encounters, unusual ally relationships, and DMs who want an NPC that surprises players who expect combat first.

Mr. Door (The Door?)

⌄

Sometimes you need an NPC that doesn't need a lot of actions but still makes a scene unforgettable. A CR 1/4 animated construct with a full stat block and genuine personality, proof that WorldSmith's NPC generator works on anything.

Grun (The Scuba Diver)

⌄

A CR 1/4 half-orc salvage specialist with a swim speed, a cursed idol under his counter, and stories wilder than the tide. Built for coastal campaigns and DMs who need a colorful background NPC that players will actually remember.

Frequently Asked Questions About the D&D Calendar Generator

How do I track time in D&D 5e?⌄

Track short rests (1 hour), long rests (8 hours), and travel time (8 hours per day at normal pace). This calendar generator automates the timeline so you can log session dates, track downtime, and never lose your campaign timeline. Built for multi-year campaigns.

How do I make a D&D calendar?⌄

Pick a preset (Forgotten Realms, Greyhawk, Eberron) or start from scratch. Name your months, set season lengths, add moons, and track phases. Click Generate to get a complete calendar with festivals, seasonal events, and lunar cycles. Export to PDF or share with your table.

What calendar does Faerûn use?⌄

Faerûn uses the Harptos calendar — 12 months (Hammer, Alturiak, Ches, Tarsakh, Mirtul, Kythorn, Flamerule, Eleasis, Eleint, Marpenoth, Uktar, Nightal) plus 5 festival days (Midwinter, Greengrass, Midsummer, Highharvestide, Feast of the Moon). This generator includes a one-click Forgotten Realms preset with the full Harptos structure.

Can I print a D&D calendar?⌄

Yes. Export your calendar to PDF and print it for your DM screen. The PDF includes month names, festival days, moon phases, and seasonal events — everything you need for session prep.

How many days are in a D&D year?⌄

The Forgotten Realms (Harptos) calendar has 365 days. Greyhawk has 364 days. Eberron has 336 days. This generator lets you customize year length for homebrew worlds — set any number of days, months, and seasons.

What are the months in the Forgotten Realms calendar?⌄

Hammer (Deepwinter), Alturiak (The Claw of Winter), Ches (The Claw of the Sunsets), Tarsakh (The Claw of the Storms), Mirtul (The Melting), Kythorn (The Time of Flowers), Flamerule (Summertide), Eleasis (Highsun), Eleint (The Fading), Marpenoth (Leaffall), Uktar (The Rotting), Nightal (The Drawing Down). Plus 5 festival days: Midwinter, Greengrass, Midsummer, Highharvestide, Feast of the Moon.

How does the Forgotten Realms calendar work?⌄

The Harptos calendar has 12 months of 30 days each, plus 5 festival days inserted between months (Midwinter after Hammer, Greengrass after Tarsakh, Midsummer after Flamerule, Highharvestide after Eleint, Feast of the Moon after Uktar). Total: 365 days. This generator includes a one-click preset with the full structure.

What's the best way to track in-game time in D&D?⌄

Log session dates on your calendar, track long rests (8 hours), and note travel time (8 hours per day at normal pace). This generator automates the timeline so you can focus on session pacing instead of date math. Export to PDF or share a live link with your players.

Can I use Google Sheets for a D&D calendar?⌄

Yes, but a dedicated generator is faster. Google Sheets requires manual setup for month names, festival days, and moon phases. This generator gives you a complete calendar in seconds with one-click presets for Forgotten Realms, Greyhawk, and Eberron. Export to PDF or share with your table.

How long should a D&D session be?⌄

3-4 hours is typical for most tables. This calendar helps you track session-to-session time so you can log how many in-game days pass between sessions. Built for campaigns that span months or years of in-game time.
