Fantasy calendar tracker

• Calendar of HarptosKeep the date in your Forgotten Realms campaign. Set the day in Dale Reckoning, add the days the party spends on the road, and see when the next festival lands.
• Calendar of GolarionKeep the date in your Pathfinder campaign. Set the day in Absalom Reckoning, add the days that pass, and see which of Golarion's holidays are coming up.
• Calendar of GalifarKeep the date in your Eberron campaign with the Calendar of Galifar. Every month is four weeks long, so the maths is easy. Following twelve moons is the hard part, and this does it for you.
• Calendar of GreyhawkKeep the date in your Greyhawk campaign. Set the day in Common Year reckoning, add the days that pass, and watch Luna and Celene as you go.
• Exandrian CalendarKeep the date in your Exandria campaign. Set the day, add the days that pass, and see the holidays and the phases of both moons.
• Barovian CalendarCount the days your party has spent in Barovia. Set the date, add each day as it passes, and keep an eye on the moon.

Keeping the date at the table

• Write the date down at the end of every session. Travel days, a long rest in town and two weeks of downtime all count, so add them up before you write it.
• Put the date at the top of each recap so your players can plan around it.
• Give your threats a date. When the date passes, something happens whether the party was there or not.
