How rate of change are calculated ?
Currencies are automatically updated in Eurecia according to Banque de France information's.
Depending on the currency, it will automatically be daily updated (yesterday's currency will be update between 1pm and 2pm, according to Paris Hour, except on weekends and bank holidays) or monthly updated (every 12th between 2am and 3am, Paris Hour).
When can I enter a currency expense?
To enter a daily expense in a foreign currency, please wait the day after, 2pm, Paris hour to inform it.
For example: you will be able to enter an expense in dollars "USD" the day after the expense was made. Eurecia will automatically convert it depending on the rate of change of the day the expense was made. So, please be careful, differentiate the day the expense was actually made and date you will type the expense.
